[SPARK-13969][ML] Add FeatureHasher transformer
This PR adds a `FeatureHasher` transformer, modeled on
[scikit-learn](http://scikit-learn.org/stable/modules/generated/sklearn.feature_extraction.FeatureHasher.html)
and [Vowpal
wabbit](https://github.com/JohnLangford/vowpal_wabbit/wiki/Feature-Hashing-and-Extraction).
The transformer operates on multiple input columns in one pass. Current
behavior is:
* for numerical columns, the values are assumed to be real values and the
feature index is `hash(columnName)` while feature value is `feature_value`
* for string columns, the values are assumed to be categorical and the
feature index is `hash(column_name=feature_value)`, while feature value is `1.0`
* For hash collisions, feature values will be summed
* `null` (missing) values are ignored
The following dataframe illustrates the basic semantics:
```
+---+------+-----+---------+------+-----------------------------------------+
|int|double|float|stringNum|string|features
|
+---+------+-----+---------+------+-----------------------------------------+
|3 |4.0 |5.0 |1 |foo
|(16,[0,8,11,12,15],[5.0,3.0,1.0,4.0,1.0])|
|6 |7.0 |8.0 |2 |bar
|(16,[0,8,11,12,15],[8.0,6.0,1.0,7.0,1.0])|
+---+------+-----+---------+------+-----------------------------------------+
```

[SPARK-21656][CORE] spark dynamic allocation should not idle timeout
executors when tasks still to run
## What changes were proposed in this pull request?
Right now spark lets go of executors when they are idle for the 60s (or
configurable time). I have seen spark let them go when they are idle but they
were really needed. I have seen this issue when the scheduler was waiting to
get node locality but that takes longer than the default idle timeout. In these
jobs the number of executors goes down really small (less than 10) but there
are still like 80,000 tasks to run.
We should consider not allowing executors to idle timeout if they are still
needed according to the number of tasks to be run.
## How was this patch tested?
Tested by manually adding executors to `executorsIdsToBeRemoved` list and
seeing if those executors were removed when there are a lot of tasks and a high
`numExecutorsTarget` value.
Code used
In `ExecutorAllocationManager.start()`
```
start_time = clock.getTimeMillis()
```
In `ExecutorAllocationManager.schedule()`
```
val executorIdsToBeRemoved = ArrayBuffer[String]()
if ( now > start_time + 1000 * 60 * 2) {
logInfo("--- REMOVING 1/2 of the EXECUTORS ---")
start_time += 1000 * 60 * 100
var counter = 0
for (x <- executorIds) {
counter += 1
if (counter == 2) {
counter = 0
executorIdsToBeRemoved += x
}
}
}

[SPARK-21603][SQL] The wholestage codegen will be much slower then that is
closed when the function is too long
## What changes were proposed in this pull request?
Close the whole stage codegen when the function lines is longer than the
maxlines which will be setted by
spark.sql.codegen.MaxFunctionLength parameter, because when the function is
too long , it will not get the JIT optimizing.
A benchmark test result is 10x slower when the generated function is too
long :

wholestagecodegen", N)

[SPARK-21680][ML][MLLIB] optimize Vector compress
## What changes were proposed in this pull request?
When use Vector.compressed to change a Vector to SparseVector, the
performance is very low comparing with Vector.toSparse.
This is because you have to scan the value three times using
Vector.compressed, but you just need two times when use Vector.toSparse.
When the length of the vector is large, there is significant performance
difference between this two method.

[SPARK-3151][BLOCK MANAGER] DiskStore.getBytes fails for files larger than
2GB
## What changes were proposed in this pull request?
introduced `DiskBlockData`, a new implementation of `BlockData`
representing a whole file.
this is somehow related to
[SPARK-6236](https://issues.apache.org/jira/browse/SPARK-6236) as well
This class follows the implementation of `EncryptedBlockData` just without
the encryption. hence:
* `toInputStream` is implemented using a `FileInputStream` (todo: encrypted
version actually uses `Channels.newInputStream`, not sure if it's the right
choice for this)
* `toNetty` is implemented in terms of `io.netty.channel.DefaultFileRegion`
* `toByteBuffer` fails for files larger than 2GB (same behavior of the
original code, just postponed a bit), it also respects the same configuration
keys defined by the original code to choose between memory mapping and simple
file read.

[SPARK-21743][SQL] top-most limit should not cause memory leak
## What changes were proposed in this pull request?
For top-most limit, we will use a special operator to execute it:
`CollectLimitExec`.
`CollectLimitExec` will retrieve `n`(which is the limit) rows from each
partition of the child plan output, see
https://github.com/apache/spark/blob/v2.2.0/sql/core/src/main/scala/org/apache/spark/sql/execution/SparkPlan.scala#L311.
It's very likely that we don't exhaust the child plan output.
This is fine when whole-stage-codegen is off, as child plan will release
the resource via task completion listener. However, when whole-stage codegen is
on, the resource can only be released if all output is consumed.
To fix this memory leak, one simple approach is, when `CollectLimitExec`
retrieve `n` rows from child plan output, child plan output should only have
`n` rows, then the output is exhausted and resource is released. This can be
done by wrapping child plan with `LocalLimit`

[SPARK-21642][CORE] Use FQDN for DRIVER_HOST_ADDRESS instead of ip address
## What changes were proposed in this pull request?
The patch lets spark web ui use FQDN as its hostname instead of ip address.
In current implementation, ip address of a driver host is set to
DRIVER_HOST_ADDRESS. This becomes a problem when we enable SSL using
"spark.ssl.enabled", "spark.ssl.trustStore" and "spark.ssl.keyStore"
properties. When we configure these properties, spark web ui is launched with
SSL enabled and the HTTPS server is configured with the custom SSL certificate
you configured in these properties.
In this case, client gets javax.net.ssl.SSLPeerUnverifiedException
exception when the client accesses the spark web ui because the client fails to
verify the SSL certificate (Common Name of the SSL cert does not match with
DRIVER_HOST_ADDRESS).
To avoid the exception, we should use FQDN of the driver host for
DRIVER_HOST_ADDRESS.
Error message that client gets when the client accesses spark web ui:
javax.net.ssl.SSLPeerUnverifiedException: Certificate for <10.102.138.239>
doesn't match any of the subject alternative names: []

[SPARK-18394][SQL] Make an AttributeSet.toSeq output order consistent
## What changes were proposed in this pull request?
This pr sorted output attributes on their name and exprId in
`AttributeSet.toSeq` to make the order consistent. If the order is different,
spark possibly generates different code and then misses cache in
`CodeGenerator`, e.g., `GenerateColumnAccessor` generates code depending on an
input attribute order.
## How was this patch tested?
Added tests in `AttributeSetSuite` and manually checked if the cache worked
well in the given query of the JIRA.

Currently the `null` field name will throw NullPointException. As a given
field name null can't be matched with any field names in json, we just output
null as its column value. This PR achieves it by returning a very unlikely
column name `__NullFieldName` in evaluation of the field names.

[SPARK-21739][SQL] Cast expression should initialize timezoneId when it is
called statically to convert something into TimestampType
## What changes were proposed in this pull request?
https://issues.apache.org/jira/projects/SPARK/issues/SPARK-21739
This issue is caused by introducing TimeZoneAwareExpression.
When the **Cast** expression converts something into TimestampType, it
should be resolved with setting `timezoneId`. In general, it is resolved in
LogicalPlan phase.
However, there are still some places that use Cast expression statically to
convert datatypes without setting `timezoneId`. In such cases,
`NoSuchElementException: None.get` will be thrown for TimestampType.
This PR is proposed to fix the issue. We have checked the whole project and
found two such usages(i.e., in`TableReader` and `HiveTableScanExec`).

[SPARK-21213][SQL] Support collecting partition-level statistics: rowCount
and sizeInBytes
## What changes were proposed in this pull request?
Added support for ANALYZE TABLE [db_name].tablename PARTITION
(partcol1[=val1], partcol2[=val2], ...) COMPUTE STATISTICS [NOSCAN] SQL command
to calculate total number of rows and size in bytes for a subset of partitions.
Calculated statistics are stored in Hive Metastore as user-defined properties
attached to partition objects. Property names are the same as the ones used to
store table-level statistics: spark.sql.statistics.totalSize and
spark.sql.statistics.numRows.
When partition specification contains all partition columns with values,
the command collects statistics for a single partition that matches the
specification. When some partition columns are missing or listed without their
values, the command collects statistics for all partitions which match a subset
of partition column values specified.
For example, table t has 4 partitions with the following specs:
* Partition1: (ds='2008-04-08', hr=11)
* Partition2: (ds='2008-04-08', hr=12)
* Partition3: (ds='2008-04-09', hr=11)
* Partition4: (ds='2008-04-09', hr=12)
'ANALYZE TABLE t PARTITION (ds='2008-04-09', hr=11)' command will collect
statistics only for partition 3.
'ANALYZE TABLE t PARTITION (ds='2008-04-09')' command will collect
statistics for partitions 3 and 4.
'ANALYZE TABLE t PARTITION (ds, hr)' command will collect statistics for
all four partitions.
When the optional parameter NOSCAN is specified, the command doesn't count
number of rows and only gathers size in bytes.
The statistics gathered by ANALYZE TABLE command can be fetched using DESC
EXTENDED [db_name.]tablename PARTITION command.

[SPARK-21773][BUILD][DOCS] Installs mkdocs if missing in the path in SQL
documentation build
## What changes were proposed in this pull request?
This PR proposes to install `mkdocs` by `pip install` if missing in the
path. Mainly to fix Jenkins's documentation build failure in
`spark-master-docs`. See
https://amplab.cs.berkeley.edu/jenkins/job/spark-master-docs/3580/console.
It also adds `mkdocs` as requirements in `docs/README.md`.
## How was this patch tested?
I manually ran `jekyll build` under `docs` directory after manually
removing `mkdocs` via `pip uninstall mkdocs`.
Also, tested this in the same way but on CentOS Linux release 7.3.1611
(Core) where I built Spark few times but never built documentation before and
`mkdocs` is not installed.

## Problem
When an RDD (particularly with a low item-per-partition ratio) is
repartitioned to numPartitions = power of 2, the resulting partitions are very
uneven-sized, due to using fixed seed to initialize PRNG, and using the PRNG
only once. See details in https://issues.apache.org/jira/browse/SPARK-21782

[SPARK-21617][SQL] Store correct table metadata when altering schema in
Hive metastore.
For Hive tables, the current "replace the schema" code is the correct
path, except that an exception in that path should result in an error, and
not in retrying in a different way.
For data source tables, Spark may generate a non-compatible Hive table;
but for that to work with Hive 2.1, the detection of data source tables
needs
to be fixed in the Hive client, to also consider the raw tables used by code
such as `alterTableSchema`.
Tested with existing and added unit tests (plus internal tests with a 2.1
metastore).
