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

             Summary: Refactor HIVE-14054 to use Collections#newSetFromMap
                 Key: HIVE-14290
                 URL: https://issues.apache.org/jira/browse/HIVE-14290
             Project: Hive
          Issue Type: Improvement
          Components: Metastore
    Affects Versions: 2.1.0
            Reporter: Peter Slawski
            Assignee: Peter Slawski
            Priority: Trivial


There is a minor refactor that can be made to HiveMetaStoreChecker so that it 
cleanly creates and uses a set that is backed by a Map implementation. In this 
case, the underlying Map implementation is ConcurrentHashMap. This refactor 
will help prevent issues such as the one reported in HIVE-14054.
