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

             Summary: Explain query fails with NPE if a client doesn't call getResultSetSchema()
                 Key: HIVE-5492
                 URL: https://issues.apache.org/jira/browse/HIVE-5492
             Project: Hive
          Issue Type: Bug
          Components: Thrift API
    Affects Versions: 0.11.0
            Reporter: Xuefu Zhang
            Assignee: Xuefu Zhang
             Fix For: 0.13.0


If a thrift client makes an explain query and fetches results without calling getResultSetSchema()
first, NullPointerException will occur in Hive.
