---------------------------------------

             Summary: fix flapping qtests - because of output string ordering
                 Key: HIVE-14329
                 URL: https://issues.apache.org/jira/browse/HIVE-14329
             Project: Hive
          Issue Type: Improvement
            Reporter: Zoltan Haindrich
            Assignee: Zoltan Haindrich
            Priority: Minor


it's a bit annoying to see some tests come and go in testresults; for example:
https://builds.apache.org/job/PreCommit-HIVE-MASTER-Build/631/testReport/org.apache.hadoop.hive.cli/TestCliDriver/testCliDriver_stats_list_bucket/history/

These tests fail occasionally because of the ordering is different in the map.

The usual cause of these failures is a simple hashmap in {{MetaDataFormatUtils}}:
https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/metadata/formatting/MetaDataFormatUtils.java#L411
