> HIVE-12366 improved the heartbeater logic by bringing down the gap between
> the lock acquisition and first heartbeat, but that's not enough, there may
> still be some issue, e.g.
> Time A: a transaction is opened
> Time B: acquireLocks is called (blocking call), but it can take a long time
> to actually acquire the locks and return if the system is busy
> Time C: as acquireLocks returns, the first heartbeat is sent
> If hive.txn.timeout < C - A, then the transaction will be timed out and
> aborted, thus causing failure.
