Subject [jira] [Commented] (HIVE-14241) Acid clashes with ConfVars.HIVEFETCHTASKCONVERSION <> "none"
Date Fri, 15 Jul 2016 16:50:20 GMT

    [ https://issues.apache.org/jira/browse/HIVE-14241?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15379659#comment-15379659
] 

Eugene Koifman commented on HIVE-14241:
---------------------------------------

The issue is not HiveConf - that is share.  The issue is that HiveConf is passed to JobConf
which copies all values from HiveConf.  So modifying HiveConf after that has no effect on
JobConf.

> Some queries are optimized so as not to create an MR job. This somehow causes the Configuration
object in FetchOperator to be passed to the operator before Driver.recordValidTxns() is called.
So then to this op it looks like there are no valid txns and it returns nothing.
