Subject [jira] [Commented] (HIVE-6721) Streaming ingest needs to be able to send many heartbeats together

Thejas M Nair commented on HIVE-6721:
-------------------------------------

Alan, I suspect the merge failures are because of commits with thrift changes that went in
yesterday. The patches with generated code usually applies fine in my experience. Can you
try regenerating the patch on latest trunk ? I think it might just work.

> 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.
