[jira] [Created] (HIVE-26242) Compaction heartbeater improvements

László Végh created HIVE-26242:
----------------------------------

             Summary: Compaction heartbeater improvements
                 Key: HIVE-26242
                 URL: https://issues.apache.org/jira/browse/HIVE-26242
             Project: Hive
          Issue Type: Improvement
            Reporter: László Végh


The Compaction heartbeater should be improved the following ways:
 * The metastore clients should be reused between heartbeats and closed only at the end, when the transaction ends
 * Instead of having a dedicated heartbeater thread for each Compaction transaction, there should be shared a heartbeater executor where the heartbeat tasks can be scheduled/submitted.
