Improve stats gathering reliability by retries on failures
----------------------------------------------------------
Key: HIVE-2127
URL: https://issues.apache.org/jira/browse/HIVE-2127
Project: Hive
Issue Type: Improvement
Reporter: Ning Zhang
Assignee: Ning Zhang
Stats publishing and aggregation only try once and if there is any exception it
will fail and return. If many mappers/reducers updating stats at the same time,
it is very common to get lock timeout. We should make stats more reliable by
retry when there is an SQLException.
