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. -- This message is automatically generated by JIRA. For more information on JIRA, see: http://www.atlassian.com/software/jira
