Subject [jira] [Commented] (HIVE-14726) delete statement fails when spdo is on
Date Fri, 09 Sep 2016 22:22:20 GMT

    [ https://issues.apache.org/jira/browse/HIVE-14726?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15478442#comment-15478442
] 

Eugene Koifman commented on HIVE-14726:
---------------------------------------

Update/Delete can certainly write many partitions at the same time, e.g.  Update T set c1=c1+1
where c2 > 100.
This may match 1 row in each partition and thus the Insert statement that is actually executed
will write to each partition.  Same for Delete.
