Alan Gates updated HIVE-6788:
-----------------------------

    Attachment: HIVE-6788.patch

This patch adds logic to getOpenTxns to check for any abandoned transactions and move them
from open to aborted before returning the list of open transactions.

> If a client abandons an open transaction it is never closed.  This does not cause any
immediate problems (as locks are timed out) but it will eventually lead to high levels of
open transactions in the lists that readers need to be aware of when reading tables or partitions.
