Subject [jira] [Updated] (HIVE-11897) JDO rollback can throw pointless exceptions
Date Sat, 19 Sep 2015 01:23:05 GMT

     [ https://issues.apache.org/jira/browse/HIVE-11897?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sergey Shelukhin updated HIVE-11897:
------------------------------------
    Description: Datanucleus does a bunch of stuff before the actual rollback, but each next
step is done in finally, so even if the prior steps fail, the rollback should still happen.
However, an exception from some questionable pre-rollback logic like manipulating resultset
after failure can affect DirectSQL fallback  (was: Datanucleus does bunch of stuff before
the actual rollback, but each next step is done in finally, so even if the prior steps fail,
the rollback should still happen. However, an exception from some questionable pre-rollback
logic like manipulating resultset after failure can affect DirectSQL fallback)
