[jira] [Commented] (HIVE-13852) NPE in TaskLocationHints during
LLAP GetSplits request
[ 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.
