Description

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.
