Subject [jira] [Commented] (HIVE-20032) Don't serialize hashCode for repartitionAndSortWithinPartitions
Date Tue, 24 Jul 2018 12:25:00 GMT

    [ https://issues.apache.org/jira/browse/HIVE-20032?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16554183#comment-16554183
] 

Rui Li commented on HIVE-20032:
-------------------------------

Hi [~stakiar], I left some comments on RB. Meanwhile, could you explain why we need to put
the registrator jar in driver's extra class path? Won't {{--jars}} add the jar to both driver
and executor's class paths? And IIUC, driver extra class path only takes jars on local FS.
So will that be a problem for cluster mode?

> Follow up on HIVE-15104, if we don't enable RDD cacheing or groupByShuffles, then we
don't need to serialize the hashCode when shuffling data in HoS.
