Subject [jira] [Commented] (HIVE-14726) delete statement fails when spdo is on
Date Fri, 09 Sep 2016 21:32:20 GMT

    [ https://issues.apache.org/jira/browse/HIVE-14726?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15478321#comment-15478321

Ashutosh Chauhan commented on HIVE-14726:
-----------------------------------------

On taking a second look it seems that delete/update statements can also be affected by wrath
of orc buffers. e.g., for the query in test case RS sort and shuffle key is ROW__ID and partition
column is in value of RS. If I understand correctly in Reducers FileSink operator need to
have an orc buffer open for each partition. This may result in similar OOM cases. However,
I am not sure if its possible to solve that problem through this optimization for delete/update
statement. [~ekoifman] [~prasanth_j] any suggestions?
