HoS would fail when scratch dir is using remote HDFS:

Path localFile = new Path(source.getPath());
Path remoteFile = new 
Path(SessionState.get().getSparkSession().getHDFSSessionDir(),
getFileName(source));
-FileSystem fileSystem = FileSystem.get(conf);
+FileSystem fileSystem = remoteFile.getFileSystem(conf);
// Overwrite if the remote file already exists. Whether the file can be 
added
// on executor is up to spark, i.e. spark.files.overwrite
fileSystem.copyFromLocalFile(false, true, localFile, remoteFile);
Path fullPath = fileSystem.getFileStatus(remoteFile).getPath();

Reporter: Dapeng Sun
Assignee: Dapeng Sun


HIVE should allow custom converting from HivePrivilegeObjectDesc to 
privilegeObject for different authorizers:

There is a case in Apache Sentry: Sentry support uri and server level 
privilege, but in hive side, it uses 
{{AuthorizationUtils.getHivePrivilegeObject(privSubjectDesc)}} to do the 
converting, and the code in {{getHivePrivilegeObject()}} only handle the scenes 
for table and database 
{noformat}
privSubjectDesc.getTable() ? HivePrivilegeObjectType.TABLE_OR_VIEW :
HivePrivilegeObjectType.DATABASE;
{noformat}

A solution is move this method to {{HiveAuthorizer}}, so that a custom 
Authorizer could enhance it.

 For a session, the scratch directory can be either a local path or a hdfs 
 scratch path. The method name createRootHDFSDir is quite confusing. So add 
 the schema information to the debug log for the troubleshooting need.

Thank [~Ferd] for the improvement, we know if the path of 
hive.exec.scratchdir was not writable, we will use this message to find the 
root cause, printing the schema info is very important for debug.

Good suggestion! Do you think it is possible to add a configuration 
{{dataformat}}, pass the argument {{dataformat}} to 
{{writeHiveRoleGrantInfo()}} and print the data format like this:
{code:java|borderStyle=solid}
SimpleDateFormat simpleDateFormat = new SimpleDateFormat(dd/MM/ HH:mm:ss);
Date grantTime = testMode ? new Date(-1) :new Date(roleGrant.getGrantTime() * 
1000L);
appendNonNull(builder, simpleDateFormat.format(grantTime));
{code}

Description: 
Currently, SHOW GRANT ROLE will return the 'grant_time' in microseconds since 
epoch. It would be nice if this were in human readable format.

Hi Owen  Alan
The feature is great!
I have a question, if the cluster enable security(Kerberos), does 
{{ZooKeeperHiveLockManager}} support a security Zookeeper? 

 Implement insert, update, and delete in Hive with full ACID support

 Key: HIVE-5317
 URL: https://issues.apache.org/jira/browse/HIVE-5317
 Project: Hive
  Issue Type: New Feature
Reporter: Owen O'Malley
Assignee: Owen O'Malley
 Fix For: 0.14.0

 Attachments: InsertUpdatesinHive.pdf


 Many customers want to be able to insert, update and delete rows from Hive 
 tables with full ACID support. The use cases are varied, but the form of the 
 queries that should be supported are:
 * INSERT INTO tbl SELECT …
 * INSERT INTO tbl VALUES ...
 * UPDATE tbl SET … WHERE …
 * DELETE FROM tbl WHERE …
 * MERGE INTO tbl USING src ON … WHEN MATCHED THEN ... WHEN NOT MATCHED THEN 
 ...
 * SET TRANSACTION LEVEL …
 * BEGIN/END TRANSACTION
 Use Cases
 * Once an hour, a set of inserts and updates (up to 500k rows) for various 
 dimension tables (eg. customer, inventory, stores) needs to be processed. The 
 dimension tables have primary keys and are typically bucketed and sorted on 
 those keys.
 * Once a day a small set (up to 100k rows) of records need to be deleted for 
 regulatory compliance.
 * Once an hour a log of transactions is exported from a RDBS and the fact 
 tables need to be updated (up to 1m rows)  to reflect the new data. The 
 transactions are a combination of inserts, updates, and deletes. The table is 
 partitioned and bucketed.
