Subject [jira] [Commented] (HIVE-13852) NPE in TaskLocationHints during LLAP GetSplits request
Date Wed, 25 May 2016 21:46:12 GMT

    [ https://issues.apache.org/jira/browse/HIVE-13852?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15300918#comment-15300918
] 

Siddharth Seth commented on HIVE-13852:
---------------------------------------

+1. What this does is ensure that each split - after grouping - is assigned to a node. With
the combination of other settings (consistent splits etc) - each grouped split should have
a location now.
We should still fix the jira where in case an LLAP node goes down, we fallback to an alternate
host.
