             Summary: In statistics annotation add flag to say if statistics is estimated or accurate
                 Key: HIVE-5949
                 URL: https://issues.apache.org/jira/browse/HIVE-5949
             Project: Hive
          Issue Type: Sub-task
          Components: Statistics
    Affects Versions: 0.13.0
            Reporter: Prasanth J
            Assignee: Prasanth J


HIVE-5921 estimates the basic statistics (row count/data size) if its not available in metastore. It will be better to have a flag which says if the statistics is estimated value or accurate value from metastore. Also basic statistics state will no longer be useful since even in worst case the state will be COMPLETE because of estimation.
