Eugene Koifman updated HIVE-11965:
----------------------------------
Issue Type: Improvement (was: Bug)
> add heartbeat count for each lock/transaction
> ---------------------------------------------
>
> Key: HIVE-11965
> URL: https://issues.apache.org/jira/browse/HIVE-11965
> Project: Hive
> Issue Type: Improvement
> Components: Transactions
> Affects Versions: 0.14.0
> Reporter: Eugene Koifman
> Assignee: Eugene Koifman
>
> We should add a HEARTBEAT_COUNT column to HIVE_LOCKS and TXNS tables so that
> queries that update LAST_HEARTBEAT also set HEARTBEAT_COUNT=HEARTBEAT_COUNT +
> 1.
> This should only be set on explicit heartbeat call, not ones resulting from
> commits, etc.
> This has low overhead but allows us to detect clients that heartbeat more
> often than is necessary thus creating useless extra load on metastore.
