Subject [jira] [Commented] (HIVE-14111) better concurrency handling for TezSessionState - part I
Date Tue, 28 Jun 2016 21:55:57 GMT

    [ https://issues.apache.org/jira/browse/HIVE-14111?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15353770#comment-15353770
] 

Sergey Shelukhin commented on HIVE-14111:
-----------------------------------------

{noformat}
    if (session == null || conf == null) {
      // TODO Will the session being passed in here be null if this is being used from the
set of default sessions.
      // Really don't see why - since SessionState can be re-used - in which case the session
will be re-used.
      return false;
    }
{noformat}
Because it's supposed to be returned to the pool and unset. Same for some other comments
