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

             Summary: NPE could be thrown in HMS when an ExpressionTree could not be made from a filter
                 Key: HIVE-14298
                 URL: https://issues.apache.org/jira/browse/HIVE-14298
             Project: Hive
          Issue Type: Bug
          Components: Metastore
            Reporter: Chaoyu Tang
            Assignee: Chaoyu Tang


In many cases where an ExpressionTree could not be made from a filter (e.g. parser fails to parse a filter etc.) and its value is null. But this null is passed around and used by a couple of HMS methods which can cause NullPointerException.
