Subject [jira] [Commented] (HIVE-14003) queries running against llap hang at times - likely due to preemption'
Date Mon, 13 Jun 2016 16:16:21 GMT

    [ https://issues.apache.org/jira/browse/HIVE-14003?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15327669#comment-15327669
] 

Siddharth Seth commented on HIVE-14003:
---------------------------------------

This is a continuation of HIVE-13858. Not all problems related to abort processing were fixed
there.

There's a window at the moment, while the RecordProcessor is being initialized where an abort
can be ignored. initialize in progress, mapOp/reduceOp not setup yet, abort received - this
sends an abort to the RecordProcessor - but it's essentially useless since it's not propagated
to the operator (which hasn't been setup yet)

Uploading a patch shortly to resolve this.

> The preemption logic in the Hive processor needs some more work. There are definitely
windows where the abort flag is completely dropped within the Hive processor.
