["Rajesh Balamohan (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HIVE-16020?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Rajesh Balamohan updated HIVE-16020:
------------------------------------
    Attachment: HIVE-16020.1.patch

Changes:
1. Common SocketFactory passed  to ContainerRunnerImpl, AMReporter, TaskRunnerCallable.
2. UserGroupInformation passed at query level (this is part of [~sseth]'s patch). Initial patch could be to provide at query level; can create subsequent jira to cache at app level.

> {{RPC.getProxy}} created in {{TaskRunnerCallable}} does not pass SocketFactory. This would cause new SocketFactory to be created every time which would cause connection reuse issues.  Also, UserGroupInformation can be reused at query level.
