 ## Building the Documentation
 
-1. Begin by cloning the `book` branch of this repository to a new directory 
that is parallel to `asf/incubator-hawq-docs`. For example:
+1. Change to the `book` directory of this repo.
 
-        $ cd /repos/asf/incubator-hawq-docs
-        $ git clone --branch book  
http://git-wip-us.apache.org/repos/asf/incubator-hawq-docs.git ../hawq-book

+$ bundle exec bookbinder bind local
+```
+
+   Bookbinder converts the XML source into HTML, and puts the final output in 
the `final_app` directory.

-title: Backing Up and Restoring HAWQ
----
-
-This chapter provides information on backing up and restoring databases in 
HAWQ system.
-
-As an administrator, you will need to back up and restore your database. HAWQ 
provides three utilities to help you back up your data:
-
--   `gpfdist`
--   PXF
--   `pg_dump`
-
-`gpfdist` and PXFÂ are parallel loading and unloading tools that provide the 
best performance. Â You can use `pg_dump`, a non-parallel utility inherited 
from PostgreSQL.
-
-In addition, in some situations you should back up your raw data from ETL 
processes.
-
-This section describes these three utilities, as well as raw data backup, to 
help you decide what fits your needs.
-
-## <a id="usinggpfdistorpxf"></a>About gpfdist and PXF 
-
-You can perform a parallel backup in HAWQ using `gpfdist` or PXFÂ to unload 
all data to external tables. Backup files can reside on a local file system or 
HDFS. To recover tables, you can load data back from external tables to the 
database.Â 
-
-### <a id="performingaparallelbackup"></a>Performing a Parallel Backup 
-
-1.  Check the database size to ensure that the file system has enough space to 
save the backed up files.
-2.  Use theÂ `pg_dump` utility to dump the schema of the target database.
-3.  Create a writable external table for each table to back up to that 
database.
-4.  Load table data into the newly created external tables.
-
->    **Note:** Put the insert statements in a single transaction to prevent 
problems if you perform any update operations during the backup.
-
-
-### <a id="restoringfromabackup"></a>Restoring from a Backup 
-
-1.  Create a database to recover to.
-2.  Recreate the schema from the schema file \(created during the `pg_dump` 
process\).
-3.  Create a readable external table for each table in the database.
-4.  Load data from the external table to the actual table.
-5.  Run the `ANALYZE` command once loading is complete. This ensures that the 
query planner generates optimal plan based on up-to-date table statistics.
-
-### <a id="differencesbetweengpfdistandpxf"></a>Differences between gpfdist 
and PXF 
-
-`gpfdist` and PXF differ in the following ways:
-
--   `gpfdist` stores backup files on local file system, while PXF stores files 
on HDFS.
--   `gpfdist` only supports plain text format, while PXF also supports binary 
format like AVRO and customized format.
--   `gpfdist` doesnât support generating compressed files, while PXF 
supports compression \(you can specify a compression codec used in Hadoop such 
as `org.apache.hadoop.io.compress.GzipCodec`\).
--   Both `gpfdist` and PXF have fast loading performance, but `gpfdist` is 
much faster than PXF.
-
-## <a id="usingpg_dumpandpg_restore"></a>About pg\_dump and pg\_restore 
-
-HAWQ supports the PostgreSQL backup and restore utilities, `pg_dump` and 
`pg_restore`. TheÂ `pg_dump`Â utility creates a single, large dump file in the 
master host containing the data from all active segments. TheÂ `pg_restore`Â 
utility restores a HAWQ database from the archive created by `pg_dump`. In most 
cases, this is probably not practical, as there is most likely not enough disk 
space in the master host for creating a single backup file of an entire 
distributed database. HAWQ supports these utilities in case you are migrating 
data from PostgreSQL to HAWQ.
-
-To create a backup archive for database `mydb`:
-
-```shell
-$ pg_dump -Ft -f mydb.tar mydb
-```
-
-To create a compressed backup using custom format and compression level 3:
-
-```shell
-$ pg_dump -Fc -Z3 -f mydb.dump mydb
-```
-
-To restore from an archive using `pg_restore`:
-
-```shell
-$ pg_restore -d new_db mydb.dump
-```
-
-## <a id="aboutbackinguprawdata"></a>About Backing Up Raw Data 
-
-Parallel backup usingÂ `gpfdist` orÂ PXFÂ works fine in most cases. There are 
a couple of situations where you cannot perform parallel backup and restore 
operations:
-
--   Performing periodically incremental backups.
--   Dumping a large data volume to external tables - this process takes a long 
time.
-
-In such situations, you can back up raw data generated during ETL processes 
and reload it into HAWQ. This provides the flexibility to choose where you 
store backup files.
-
-## <a id="estimatingthebestpractice"></a>Selecting a Backup Strategy/Utility

discussed above.Â

-## <a id="estimatingspacerequirements"></a>Estimating Space Requirements 
-
-Before you back up your database, ensure that you have enough space to store 
backup files. This section describes how to get the database size and estimate 
space requirements.
-
--   Use `hawq_toolkit` to query size of the database you want to backup.Â 
-
-    ```
-    mydb=# SELECT sodddatsize FROM hawq_toolkit.hawq_size_of_database WHERE 
sodddatname=âmydbâ;
-    ```
-
-    If tables in your database are compressed, this query shows the compressed 
size of the database.
-
--   Estimate the total size of the backup files.
-    -   If your database tables and backup files are both compressed, you can 
use the value `sodddatsize` as an estimate value.
-    -   If your database tables are compressed Â and backup files are not, you 
need to multiply `sodddatsize` by the compression ratio. Although this depends 
on the compression algorithms, you can use an empirical value such as 300%.
-    -   If your back files are compressed and database tables are not, you 
need to divide `sodddatsize` by the compression ratio.
--   Get space requirement.
-    -   If you use HDFS with PXF, the space requirement is 
`size_of_backup_files * replication_factor`.
-
-    -   If you use gpfdist, the space requirement for each gpfdist instance is 
`size_of_backup_files / num_gpfdist_instances`Â sinceÂ table data will be 
evenly distributed to all `gpfdist` instances.
-
-
-## <a id="usinggpfdist"></a>Using gpfdist 
-
-This section discusses `gpfdist` and shows an example of how to backup and 
restore HAWQ database.
-
-`gpfdist` is HAWQâs parallel file distribution program. It is used by 
readable external tables and `hawq load` to serve external table files to all 
HAWQ segments in parallel. It is used by writable external tables to accept 
output streams from HAWQ segments in parallel and write them out to a file.
-
-To use `gpfdist`, start the `gpfdist` server program on the host where you 
want to store backup files. You can start multiple `gpfdist` instances on the 
same host or on different hosts. For each `gpfdist` instance, you specify a 
directory from which `gpfdist` will serve files for readable external tables or 
create output files for writable external tables. For example, if you have a 
dedicated machine for backup with two disks, you can start two `gpfdist` 
instances, each using one disk:
-
-![](../mdimages/gpfdist_instances_backup.png "Deploying multiple gpfdist 
instances on a backup host")
-
-You can also run `gpfdist` instances on each segment host. During backup, 
table data will be evenly distributed to all `gpfdist` instances specified in 
the `LOCATION` clause in the `CREATE EXTERNAL TABLE` definition.
-
-![](../mdimages/gpfdist_instances.png "Deploying gpfdist instances on each 
segment host")
-
-### <a id="example"></a>Example 
-
-This example of using `gpfdist`Â backs up and restores a 1TB `tpch` database. 
To do so, start two `gpfdist` instances on the backup host `sdw1` with two 1TB 
disks \(One disk mounts at `/data1`, another disk mounts at `/data2`\).
-
-#### <a id="usinggpfdisttobackupthetpchdatabase"></a>Using gpfdist to Back Up 
the tpch Database 
-
-1.  Create backup locations and start the `gpfdist` instances.
-
-    In this example, issuing the first command creates two folders on two 
different disks with the same postfix `backup/tpch_20140627`. These folders are 
labeled as backups of the `tpch` database on 2014-06-27. In the next two 
commands, the example shows two `gpfdist` instances, one using port 8080, and 
another using port 8081:
-
-    ```shell
-    sdw1$ mkdir -p /data1/gpadmin/backup/tpch_20140627 
/data2/gpadmin/backup/tpch_20140627
-    sdw1$ gpfdist -d /data1/gpadmin/backup/tpch_20140627 -p 8080 &
-    sdw1$ gpfdist -d /data2/gpadmin/backup/tpch_20140627 -p 8081 &
-    ```
-
-2.  Save the schema for the database:
-
-    ```shell
-    master_host$ pg_dump --schema-only -f tpch.schema tpch
-    master_host$ scp tpch.schema sdw1:/data1/gpadmin/backup/tpch_20140627
-    ```
-
-    On the HAWQ master host, use theÂ `pg_dump` utility to save the schema of 
the tpch database to the file tpch.schema. Copy the schema file to the backup 
location to restore the database schema.
-
-3.  Create a writable external table for each table in the database:
-
-    ```shell
-    master_host$ psql tpch
-    ```
-    ```sql
-    tpch=# CREATE WRITABLE EXTERNAL TABLE wext_orders (LIKE orders)
-    tpch-# LOCATION('gpfdist://sdw1:8080/orders1.csv', 
'gpfdist://sdw1:8081/orders2.csv') FORMAT 'CSV';
-    tpch=# CREATE WRITABLE EXTERNAL TABLE wext_lineitem (LIKE lineitem)
-    tpch-# LOCATION('gpfdist://sdw1:8080/lineitem1.csv', 
'gpfdist://sdw1:8081/lineitem2.csv') FORMAT 'CSV';
-    ```
-
-    The sample shows two tables in the `tpch` database: `orders` andÂ `line 
item`. The sample shows that two corresponding external tables are created. 
Specify a location or each `gpfdist` instance in the `LOCATION` clause. This 
sample uses the CSV text format here, but you can also choose other delimited 
text formats. For more information, see the `CREATE EXTERNAL TABLE` SQL command.
-
-4.  Unload data to the external tables:
-
-    ```sql
-    tpch=# BEGIN;
-    tpch=# INSERT INTO wext_orders SELECT * FROM orders;
-    tpch=# INSERT INTO wext_lineitem SELECT * FROM lineitem;
-    tpch=# COMMIT;
-    ```
-
-5.  **\(Optional\)** Stop `gpfdist` servers to free ports for other processes:
-
-    Find the progress ID and kill the process:
-
-    ```shell
-    sdw1$ ps -ef | grep gpfdist
-    sdw1$ kill 612368; kill 612369
-    ```
-
-
-#### <a id="torecoverusinggpfdist"></a>Recovering Using gpfdist 
-
-1.  Restart `gpfdist` instances if they arenât running:
-
-    ```shell
-    sdw1$ gpfdist -d /data1/gpadmin/backup/tpch_20140627 -p 8080 &
-    sdw1$ gpfdist -d /data2/gpadmin/backup/tpch_20140627 -p 8081 &
-    ```
-
-2.  Create a new database and restore the schema:
-
-    ```shell
-    master_host$ createdb tpch2
-    master_host$ scp sdw1:/data1/gpadmin/backup/tpch_20140627/tpch.schema .
-    master_host$ psql -f tpch.schema -d tpch2
-    ```
-
-3.  Create a readable external table for each table:
-
-    ```shell
-    master_host$ psql tpch2
-    ```
-    
-    ```sql
-    tpch2=# CREATE EXTERNAL TABLE rext_orders (LIKE orders) 
LOCATION('gpfdist://sdw1:8080/orders1.csv', 'gpfdist://sdw1:8081/orders2.csv') 
FORMAT 'CSV';
-    tpch2=# CREATE EXTERNAL TABLE rext_lineitem (LIKE lineitem) 
LOCATION('gpfdist://sdw1:8080/lineitem1.csv', 
'gpfdist://sdw1:8081/lineitem2.csv') FORMAT 'CSV';
-    ```
-
-    **Note:** The location clause is the same as the writable external table 
above.
-
-4.  Load data back from external tables:
-
-    ```sql
-    tpch2=# INSERT INTO orders SELECT * FROM rext_orders;
-    tpch2=# INSERT INTO lineitem SELECT * FROM rext_lineitem;
-    ```
-
-5.  Run the `ANALYZE` command after data loading:
-
-    ```sql
-    tpch2=# analyze;
-    ```
-
-
-### <a id="troubleshootinggpfdist"></a>Troubleshooting gpfdist 
-
-Keep in mind that `gpfdist` is accessed at runtime by the segment instances. 
Therefore, you must ensure that the HAWQ segment hosts have network access to 
gpfdist. Since the `gpfdist` program is a Â web server, to test connectivity 
you can run the following command from each host in your HAWQ array \(segments 
and master\):
-
-```shell
-$ wget http://gpfdist_hostname:port/filename
-```
-
-Also, make sure that your `CREATE EXTERNAL TABLE` definition has the correct 
host name, port, and file names for `gpfdist`. The file names and paths 
specified should be relative to the directory where gpfdist is serving files 
\(the directory path used when you started the `gpfdist` program\). See 
âDefining External Tables - Examplesâ.
-
-## <a id="usingpxf"></a>Using PXF 
-
-HAWQ Extension Framework \(PXF\) is an extensible framework that allows HAWQ 
to query external system data. The details of how to install and use PXF can be 
found in [Using PXF with Unmanaged Data](../pxf/HawqExtensionFrameworkPXF.html).
-
-### <a id="usingpxftobackupthetpchdatabase"></a>Using PXF to Back Up the tpch 
Database 
-
-1.  Create a folder on HDFS for this backup:
-
-    ```shell
-    master_host$ hdfs dfs -mkdir -p /backup/tpch-2014-06-27
-    ```
-
-2.  Dump the database schema using `pg_dump` and store the schema file in a 
backup folder:
-
-    ```shell
-    master_host$ pg_dump --schema-only -f tpch.schema tpch
-    master_host$ hdfs dfs -copyFromLocal tpch.schema /backup/tpch-2014-06-27
-    ```
-
-3.  Create a writable external table for each table in the database:
-
-    ```shell
-    master_host$ psql tpch
-    ```
-    
-    ```sql
-    tpch=# CREATE WRITABLE EXTERNAL TABLE wext_orders (LIKE orders)
-    tpch-# LOCATION('pxf://namenode_host:51200/backup/tpch-2014-06-27/orders'
-    tpch-#           '?Profile=HdfsTextSimple'
-    tpch-#           
'&COMPRESSION_CODEC=org.apache.hadoop.io.compress.SnappyCodec'
-    tpch-#          )
-    tpch-# FORMAT 'TEXT';
-
-    tpch=# CREATE WRITABLE EXTERNAL TABLE wext_lineitem (LIKE lineitem)
-    tpch-# LOCATION('pxf://namenode_host:51200/backup/tpch-2014-06-27/lineitem'
-    tpch-#           '?Profile=HdfsTextSimple'
-    tpch-#           
'&COMPRESSION_CODEC=org.apache.hadoop.io.compress.SnappyCodec')
-    tpch-# FORMAT 'TEXT';
-    ```
-
-    Here, all backup files for the `orders` table go in the 
/backup/tpch-2014-06-27/orders folder, all backup files for the `lineitem` 
table go in /backup/tpch-2014-06-27/lineitem folder. We use snappy compression 
to save disk space.
-
-4.  Unload the data to external tables:
-
-    ```sql
-    tpch=# BEGIN;
-    tpch=# INSERT INTO wext_orders SELECT * FROM orders;
-    tpch=# INSERT INTO wext_lineitem SELECT * FROM lineitem;
-    tpch=# COMMIT;
-    ```
-
-5.  **\(Optional\)** Change the HDFS file replication factor for the backup 
folder. HDFS replicates each block into three blocks by default for 
reliability. You can decrease this number for your backup files if you need to:
-
-    ```shell
-    master_host$ hdfs dfs -setrep 2 /backup/tpch-2014-06-27
-    ```
-
-    **Note:** This only changes the replication factor for existing files; new 
files will still use the default replication factor.
-
-
-### <a id="torecoverfromapxfbackup"></a>Recovering a PXF Backup 
-
-1.  Create a new database and restore the schema:
-
-    ```shell
-    master_host$ createdb tpch2
-    master_host$ hdfs dfs -copyToLocal /backup/tpch-2014-06-27/tpch.schema .
-    master_host$ psql -f tpch.schema -d tpch2
-    ```
-
-2.  Create a readable external table for each table to restore:
-
-    ```shell
-    master_host$ psql tpch2
-    ```
-    
-    ```sql
-    tpch2=# CREATE EXTERNAL TABLE rext_orders (LIKE orders)
-    tpch2-# 
LOCATION('pxf://namenode_host:51200/backup/tpch-2014-06-27/orders?Profile=HdfsTextSimple')
-    tpch2-# FORMAT 'TEXT';
-    tpch2=# CREATE EXTERNAL TABLE rext_lineitem (LIKE lineitem)
-    tpch2-# 
LOCATION('pxf://namenode_host:51200/backup/tpch-2014-06-27/lineitem?Profile=HdfsTextSimple')
-    tpch2-# FORMAT 'TEXT';
-    ```
-
-    The location clause is almost the same as above, except you donât have 
to specify the `COMPRESSION_CODEC` because PXF will automatically detect it.
-
-3.  Load data back from external tables:
-
-    ```sql
-    tpch2=# INSERT INTO ORDERS SELECT * FROM rext_orders;
-    tpch2=# INSERT INTO LINEITEM SELECT * FROM rext_lineitem;
-    ```
-
-4.  Run `ANALYZE` after data loading:
-
-    ```sql
-    tpch2=# ANALYZE;
-    ```

-title: Expanding a Cluster
----
-
-Apache HAWQ supports dynamic node expansion. You can add segment nodes while 
HAWQ is running without having to suspend or terminate cluster operations.
-
-**Note:** This topic describes how to expand a cluster using the command-line 
interface. If you are using Ambari to manage your HAWQ cluster, see [Expanding 
the HAWQ Cluster](../admin/ambari-admin.html#amb-expand) in [Managing HAWQ 
Using Ambari](../admin/ambari-admin.html)
-
-## <a id="topic_kkc_tgb_h5"></a>Guidelines for Cluster Expansion 
-
-This topic provides some guidelines around expanding your HAWQ cluster.
-
-There are several recommendations to keep in mind when modifying the size of 
your running HAWQ cluster:
-
--   When you add a new node, install both a DataNode and a physical segment on 
the new node. If you are using YARN to manage HAWQ resources, you must also 
configure a YARN NodeManager on the new node.
--   After adding a new node, you should always rebalance HDFS data to maintain 
cluster performance.
--   Adding or removing a node also necessitates an update to the HDFS metadata 
cache. This update will happen eventually, but can take some time. To speed the 
update of the metadata cache, execute **`select gp_metadata_cache_clear();`**.
--   Note that for hash distributed tables, expanding the cluster will not 
immediately improve performance since hash distributed tables use a fixed 
number of virtual segments. In order to obtain better performance with hash 
distributed tables, you must redistribute the table to the updated cluster by 
either the [ALTER TABLE](../reference/sql/ALTER-TABLE.html) or [CREATE TABLE 
AS](../reference/sql/CREATE-TABLE-AS.html) command.
--   If you are using hash tables, consider updating the 
`default_hash_table_bucket_number` server configuration parameter to a larger 
value after expanding the cluster but before redistributing the hash tables.
-
-## <a id="task_hawq_expand"></a>Adding a New Node to an Existing HAWQ Cluster 
-
-The following procedure describes the steps required to add a node to an 
existing HAWQ cluster.  First ensure that the new node has been configured per 
the instructions found in [Apache HAWQ System 
Requirements](../requirements/system-requirements.html) and [Select HAWQ Host 
Machines](../install/select-hosts.html).
-
-For example purposes in this procedure, we are adding a new node named `sdw4`.
-
-1.  Prepare the target machine by checking operating system configurations and 
passwordless ssh. HAWQ requires passwordless ssh access to all cluster nodes. 
To set up passwordless ssh on the new node, perform the following steps:
-    1.  Login to the master HAWQ node as gpadmin. If you are logged in as a 
different user, switch to the gpadmin user and source the `greenplum_path.sh` 
file.
-
-        ```shell
-        $ su - gpadmin
-        $ source /usr/local/hawq/greenplum_path.sh
-        ```
-
-    2.  On the HAWQ master node, change directories to /usr/local/hawq/etc. In 
this location, create a file called `new_hosts` and add the hostname\(s\) of 
the node\(s\) you wish to add to the existing HAWQ cluster, one per line. For 
example:
-
-        ```
-        sdw4
-        ```
-
-    3.  Login to the master HAWQ node as root and source the 
`greenplum_path.sh` file.
-
-        ```shell
-        $ su - root
-        $ source /usr/local/hawq/greenplum_path.sh
-        ```
-
-    4.  Execute the following hawq command to set up passwordless ssh for root 
on the new host machine:
-
-        ```shell
-        $ hawq ssh-exkeys -e hawq_hosts -x new_hosts
-        ```
-
-    5.  Create the gpadmin user on the new host\(s\).
-
-        ```shell
-        $ hawq ssh -f new_hosts -e '/usr/sbin/useradd gpadmin'
-        $ hawq ssh âf new_hosts -e 'echo -e "changeme\changeme" | passwd 
gpadmin'
-        ```
-
-    6.  Switch to the gpadmin user and source the `greenplum_path.sh` file 
again.
-
-        ```shell
-        $ su - gpadmin
-        $ source /usr/local/hawq/greenplum_path.sh
-        ```
-
-    7.  Execute the following hawq command a second time to set up 
passwordless ssh for the gpadmin user:
-
-        ```shell
-        $ hawq ssh-exkeys -e hawq_hosts -x new_hosts
-        ```
-
-    8.  (Optional) If you enabled temporary password-based authentication 
while preparing/configuring your new HAWQ host system, turn off password-based 
authentication as described in [Apache HAWQ System 
Requirements](../requirements/system-requirements.html#topic_pwdlessssh).
-
-    8.  After setting up passwordless ssh, you can execute the following hawq 
command to check the target machine's configuration.
-
-        ```shell
-        $ hawq check -f new_hosts
-        ```
-
-        Configure operating system parameters as needed on the host machine. 
See the HAWQ installation documentation for a list of specific operating system 
parameters to configure.
-
-2.  Login to the target host machine `sdw4` as the root user. If you are 
logged in as a different user, switch to the root account:
-
-    ```shell
-    $ su - root
-    ```
-
-3.  If not already installed, install the target machine \(`sdw4`\) as an HDFS 
DataNode.
-4.  If you have any user-defined function (UDF) libraries installed in your 
existing HAWQ cluster, install them on the new node.
-4.  Download and install HAWQ on the target machine \(`sdw4`\) as described in 
the [software build 
instructions](https://cwiki.apache.org/confluence/display/HAWQ/Build+and+Install)
 or in the distribution installation documentation.
-5.  On the HAWQ master node, check current cluster and host information using 
`psql`.
-
-    ```shell
-    $ psql -d postgres
-    ```
-    
-    ```sql
-    postgres=# SELECT * FROM gp_segment_configuration;
-    ```
-    
-    ```
-     registration_order | role | status | port  | hostname |    address    
-    --------------------+------+--------+-------+----------+---------------
-                     -1 | s    | u      |  5432 | sdw1     | 192.0.2.0
-                      0 | m    | u      |  5432 | mdw      | rhel64-1
-                      1 | p    | u      | 40000 | sdw3     | 192.0.2.2
-                      2 | p    | u      | 40000 | sdw2     | 192.0.2.1
-    (4 rows)
-    ```
-
-    At this point the new node does not appear in the cluster.
-
-6.  Execute the following command to confirm that HAWQ was installed on the 
new host:
-
-    ```shell
-    $ hawq ssh -f new_hosts -e "ls -l $GPHOME"
-    ```
-
-7.  On the master node, use a text editor to add hostname `sdw4` into the 
`hawq_hosts` file you created during HAWQ installation. \(If you do not already 
have this file, then you create it first and list all the nodes in your 
cluster.\)
-
-    ```
-    mdw
-    smdw
-    sdw1
-    sdw2
-    sdw3
-    sdw4
-    ```
-
-8.  On the master node, use a text editor to add hostname `sdw4` to the 
`$GPHOME/etc/slaves` file. This file lists all the segment host names for your 
cluster. For example:
-
-    ```
-    sdw1
-    sdw2
-    sdw3
-    sdw4
-    ```
-
-9.  Sync the `hawq-site.xml` and `slaves` configuration files to all nodes in 
the cluster \(as listed in hawq\_hosts\).
-
-    ```shell
-    $ hawq scp -f hawq_hosts hawq-site.xml slaves =:$GPHOME/etc/
-    ```
-
-10. Make sure that the HDFS DataNode service has started on the new node.
-11. On `sdw4`, create directories based on the values assigned to the 
following properties in `hawq-site.xml`. These new directories must be owned by 
the same database user \(for example, `gpadmin`\) who will execute the `hawq 
init segment` command in the next step.
-    -   `hawq_segment_directory`
-    -   `hawq_segment_temp_directory`
-    **Note:** The `hawq_segment_directory` must be empty.
-
-12. On `sdw4`, switch to the database user \(for example, `gpadmin`\), and 
initalize the segment.
-
-    ```shell
-    $ su - gpadmin
-    $ hawq init segment
-    ```
-
-13. On the master node, check current cluster and host information using 
`psql` to verify that the new `sdw4` node has initialized successfully.
-
-    ```shell
-    $ psql -d postgres
-    ```
-    
-    ```sql
-    postgres=# SELECT * FROM gp_segment_configuration ;
-    ```
-    
-    ```
-     registration_order | role | status | port  | hostname |    address    
-    --------------------+------+--------+-------+----------+---------------
-                     -1 | s    | u      |  5432 | sdw1     | 192.0.2.0
-                      0 | m    | u      |  5432 | mdw      | rhel64-1
-                      1 | p    | u      | 40000 | sdw3     | 192.0.2.2
-                      2 | p    | u      | 40000 | sdw2     | 192.0.2.1
-                      3 | p    | u      | 40000 | sdw4     | 192.0.2.3
-    (5 rows)
-    ```
-
-14. To maintain optimal cluster performance, rebalance HDFS data by running 
the following command:
-15. 
-    ```shell
-    $ sudo -u hdfs hdfs balancer -threshold threshold_value
-    ```
-    
-    where *threshold\_value* represents how much a DataNode's disk usage, in 
percentage, can differ from overall disk usage in the cluster. Adjust the 
threshold value according to the needs of your production data and disk. The 
smaller the value, the longer the rebalance time.
->
-    **Note:** If you do not specify a threshold, then a default value of 20 is 
used. If the balancer detects that a DataNode is using less than a 20% 
difference of the cluster's overall disk usage, then data on that node will not 
be rebalanced. For example, if disk usage across all DataNodes in the cluster 
is 40% of the cluster's total disk-storage capacity, then the balancer script 
ensures that a DataNode's disk usage is between 20% and 60% of that DataNode's 
disk-storage capacity. DataNodes whose disk usage falls within that percentage 
range will not be rebalanced.
-
-    Rebalance time is also affected by network bandwidth. You can adjust 
network bandwidth used by the balancer by using the following command:
-    
-    ```shell
-    $ sudo -u hdfs hdfs dfsadmin -setBalancerBandwidth network_bandwith
-    ```
-    
-    The default value is 1MB/s. Adjust the value according to your network.
-
-15. Speed up the clearing of the metadata cache by using the following command:
-
-    ```shell
-    $ psql -d postgres
-    ```
-    
-    ```sql
-    postgres=# SELECT gp_metadata_cache_clear();
-    ```
-
-16. After expansion, if the new size of your cluster is greater than or equal 
\(#nodes >=4\) to 4, change the value of the 
`output.replace-datanode-on-failure` HDFS parameter in `hdfs-client.xml` to 
`false`.
-
-17. (Optional) If you are using hash tables, adjust the 
`default_hash_table_bucket_number` server configuration property to reflect the 
cluster's new size. Update this configuration's value by multiplying the new 
number of nodes in the cluster by the appropriate amount indicated below.
-
-       |Number of Nodes After Expansion|Suggested 
default\_hash\_table\_bucket\_number value|
-       |---------------|------------------------------------------|
-       |<= 85|6 \* \#nodes|
-       |\> 85 and <= 102|5 \* \#nodes|
-       |\> 102 and <= 128|4 \* \#nodes|
-       |\> 128 and <= 170|3 \* \#nodes|
-       |\> 170 and <= 256|2 \* \#nodes|
-       |\> 256 and <= 512|1 \* \#nodes|
-       |\> 512|512| 
-   
-18. If you are using hash distributed tables and wish to take advantage of the 
performance benefits of using a larger cluster, redistribute the data in all 
hash-distributed tables by using either the [ALTER 
TABLE](../reference/sql/ALTER-TABLE.html) or [CREATE TABLE 
AS](../reference/sql/CREATE-TABLE-AS.html) command. You should redistribute the 
table data if you modified the `default_hash_table_bucket_number` configuration 
parameter. 
-
-
-       **Note:** The redistribution of table data can take a significant 
amount of time.

-title: Removing a Node
----
-
-This topic outlines the proper procedure for removing a node from a HAWQ 
cluster.
-
-In general, you should not need to remove nodes manually from running HAWQ 
clusters. HAWQ isolates any nodes that HAWQ detects as failing due to hardware 
or other types of errors.
-
-## <a id="topic_p53_ct3_kv"></a>Guidelines for Removing a Node 
-
-If you do need to remove a node from a HAWQ cluster, keep in mind the 
following guidelines around removing nodes:
-
--   Never remove more than two nodes at a time since the risk of data loss is 
high.
--   Only remove nodes during system maintenance windows when the cluster is 
not busy or running queries.
-
-## <a id="task_oy5_ct3_kv"></a>Removing a Node from a Running HAWQ Cluster 
-
-The following is a typical procedure to remove a node from a running HAWQ 
cluster:
-
-1.  Login as gpadmin to the node that you wish to remove and source 
`greenplum_path.sh`.
-
-    ```shell
-    $ su - gpadmin
-    $ source /usr/local/hawq/greenplum_path.sh
-    ```
-
-2.  Make sure that there are no running QEs on the segment. Execute the 
following command to check for running QE processes:
-
-    ```shell
-    $ ps -ef | grep postgres
-    ```
-
-    In the output, look for processes that contain SQL commands such as INSERT 
or SELECT. For example:
-
-    ```shell
-    [gpadmin@rhel64-3 ~]$ ps -ef | grep postgres
-    gpadmin 3000 2999 0 Mar21 ? 00:00:08 postgres: port 40000, logger process
-    gpadmin 3003 2999 0 Mar21 ? 00:00:03 postgres: port 40000, stats collector 
process
-    gpadmin 3004 2999 0 Mar21 ? 00:00:50 postgres: port 40000, writer process
-    gpadmin 3005 2999 0 Mar21 ? 00:00:06 postgres: port 40000, checkpoint 
process
-    gpadmin 3006 2999 0 Mar21 ? 00:01:25 postgres: port 40000, segment 
resource manager
-    gpadmin 7880 2999 0 02:08 ? 00:00:00 postgres: port 40000, gpadmin 
postgres 192.0.2.0(33874) con11 seg0 cmd18 MPPEXEC INSERT
-    ```
-
-3.  Stop hawq on this segment by executing the following command:
-
-    ```shell
-    $ hawq stop segment
-    ```
-
-4.  On HAWQ master, remove the hostname of the segment from the `slaves` file. 
Then sync the `slaves` file to all nodes in the cluster by executing the 
following command:
-
-    ```shell
-    $ hawq scp -f hostfile slaves =:  $GPHOME/etc/slaves
-    ```
