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

             Summary: NullPointerException in a mixed 1.1 / 1.2 cluster
                 Key: CASSANDRA-5334
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-5334
             Project: Cassandra
          Issue Type: Bug
    Affects Versions: 1.1.9
            Reporter: Ryan McGuire


I have a mixed version cluster consisting of two 1.1.9 nodes and one 1.2.2 node upgraded from
1.1.9. 

The upgrade works, and I don't see any problems end user problems, however I see this exception
in the logs on the non-upgraded nodes:

{code}

Steps to reproduce:
{code}
ccm create -v 1.1.9 1.1.9
ccm populate -n 3
ccm start
ccm node1 stress
ccm node1 down
{code}

edit ~/.ccm/1.1.9/cluster.conf and configure cassandra_dir to point to 1.2.2

{code}
ccm node1 up
{code}

The cluster is now a mixed version, and works for user queries, but with the exception above.
