Subject [jira] [Commented] (HIVE-14574) use consistent hashing for LLAP consistent splits to alleviate impact from cluster changes
Date Thu, 18 Aug 2016 21:50:20 GMT

    [ https://issues.apache.org/jira/browse/HIVE-14574?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15427219#comment-15427219
] 

Siddharth Seth commented on HIVE-14574:
---------------------------------------

bq. block boundaries and stripe boundaries
I'n not sure why this comment was even added in there. In terms of the 3 byte difference in
ORC - [~prasanth_j] may have fixed that already.

Will Hashing.consistentHash generate the same values across different JVMs ? I think I had
considered this earlier, and finally went with murmur since that does generate the same value
across different JVMs / machines.

Needs new unit tests to validate behaviour. Don't think there's any reasons for the existing
ones to break.
