------------------------------------
Hi [~jcamachorodriguez],
Both me and [~dkuzmenko] checked this, and we are confident that abortTxns is
handled in one single MySQL transaction on the HMS side. Unless there is a
misunderstanding regarding your requirement on our side, I think this can be
closed. :)

> Logic in `abortTxns` should be executed in a single transaction, rather than
> multiple ones. Otherwise, if you restart HMS between txn abort and the lock
> deletion, we end up with orphaned locks.
