> When Hive query is being interrupted via cancel request, both the background
> pool thread (HiveServer2-Background) executing the query and the HttpHandler
> thread (HiveServer2-Handler) running the HiveSession.cancelOperation logic
> will eventually trigger the below method:
> {code}
> DriverTxnHandler.endTransactionAndCleanup(boolean commit)
> {code}
> Since this method could be invoked concurrently we need to synchronize access
> to it, so that only 1 thread would attempt to abort the transaction and stop
> the heartbeat.
