Subject [jira] [Commented] (HIVE-11515) Still some possible race condition in DynamicPartitionPruner
Date Mon, 24 Aug 2015 20:11:46 GMT

    [ https://issues.apache.org/jira/browse/HIVE-11515?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14709976#comment-14709976

Siddharth Seth commented on HIVE-11515:
---------------------------------------

[~navis] - I think the patch is good to go in except for the log line, which should be an
error.

However, I don't see this fixing an issue - I believe the condition mentioned is already handled.
Up to you if you want to commit this.

> Even after HIVE-9976, I could see race condition in DPP sometimes. Hard to reproduce
but it seemed related to the fact that prune() is called by thread-pool. With some delay in
queue, events from fast tasks are arrived before prune() is called.
