[jira] Created: (HIVE-1653) Ability to enforce correct stats

Ability to enforce correct stats
--------------------------------

                 Key: HIVE-1653
                 URL: https://issues.apache.org/jira/browse/HIVE-1653
             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 one of the mappers/reducers cannot publish stats, it may lead to wrong aggregated stats.
There should be a way to avoid this - at the least, a configuration variable which fails the 
task if stats cannot be published
