Subject [jira] [Created] (HIVE-3933) StatsWork of QueryPlan can't be serialized correctly
Date Thu, 24 Jan 2013 02:07:17 GMT
yi created HIVE-3933:
------------------------

             Summary: StatsWork of QueryPlan can't be serialized correctly
                 Key: HIVE-3933
                 URL: https://issues.apache.org/jira/browse/HIVE-3933
             Project: Hive
          Issue Type: Bug
          Components: Serializers/Deserializers
            Reporter: yi
            Priority: Minor


QueryPlan is serialized using java.beans.XMLEncoder, but StatsWork of QueryPlan doesn't not
follow java bean syntax, so it can't be serialized correctly.

java.lang.NullPointerException
