Subject [jira] [Commented] (HIVE-16296) use LLAP executor count to configure reducer auto-parallelism
Date Tue, 04 Apr 2017 20:34:42 GMT

    [ https://issues.apache.org/jira/browse/HIVE-16296?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15955760#comment-15955760

Gopal V commented on HIVE-16296:
--------------------------------

This is a bit strange - I think HDFS has some consistent ordering of files in a directory
when listing it. 

I'm getting consistent results without an ORDER BY (i.e the output files are read in reducer
order - reducer 0 files first etc.).
