[jira] [Comment Edited] (HIVE-14241) Acid clashes with ConfVars.HIVEFETCHTASKCONVERSION <> "none"

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

The issue is not HiveConf - that is shared.  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.
