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.
> RetryingRawStore logic needs to be significantly reworked to support retries
> within transactions
