[jira] Created: (HIVE-1652) Delete temporary stats data after some time

Delete temporary stats data after some time
-------------------------------------------

                 Key: HIVE-1652
                 URL: https://issues.apache.org/jira/browse/HIVE-1652
             Project: Hadoop Hive
          Issue Type: Improvement
          Components: Query Processor
            Reporter: Namit Jain
            Assignee: Ning Zhang
             Fix For: 0.7.0


This is a follow-up for https://issues.apache.org/jira/browse/HIVE-1361.
If the client dies after some stats have been published, there is no way to clean that data.

A simple work-around might be to add current timestamp in the data - and a background process
to clean up old stats.
