Subject [jira] [Commented] (HIVE-3484) RetryingRawStore logic needs to be significantly reworked to support retries within transactions
Date Sat, 22 Sep 2012 01:46:07 GMT

    [ https://issues.apache.org/jira/browse/HIVE-3484?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13460998#comment-13460998
] 

Kevin Wilfong commented on HIVE-3484:
-------------------------------------

We have seen in the past errors where the connection to MySQL will be lost and hence the transaction
is broken, but the RetryingRawStore happily retries the command to the RawStore, in which
the connection is reestablished and the command succeeds, and continues with the rest of the
commands.  These commands are performed outside a transaction and ultimately the command fails
because the number of transactions the metastore tries to close at the end does not match
the number of open transactions.
