> The heartbeat method added to HiveMetaStoreClient is intended for SQL operations where
the user will have one transaction and a hand full of locks.  But in the streaming ingest
case the client opens a batch of transactions together.  In this case we need a way for the
client to send a heartbeat for this batch of transactions rather than being forced to send
the heartbeats one at a time.
