Date Fri, 18 May 2012 14:59:07 GMT
Maryann Xue created HBASE-6049:
----------------------------------

             Summary: Serializing "List" containing null elements will cause NullPointerException
in HbaseObjectWritable.writeObject()
                 Key: HBASE-6049
                 URL: https://issues.apache.org/jira/browse/HBASE-6049
             Project: HBase
          Issue Type: Bug
          Components: io
    Affects Versions: 0.94.0
            Reporter: Maryann Xue


An error case could be in Coprocessor AggregationClient, the median() function handles an
empty region and returns a List Object with the first element as a Null value. NPE occurs
in the RPC response stage and the response never gets sent.
