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

             Summary: ClassCastException during Status
                 Key: CASSANDRA-12942
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-12942
             Project: Cassandra
          Issue Type: Bug
          Components: Tools
         Environment: Cassandra 3.7
OpenJDK 8
Ubuntu 14.04
            Reporter: Chris Donati
            Priority: Minor


I often encounter a ClassCastException when trying to run `nodetool status` on a particular cluster. Occasionally, the command will work on one of the nodes (and report all of the nodes as 'UN'), but the majority of the time, nodetool raises the following exception:
{noformat}
error: null
-- StackTrace --
java.lang.ClassCastException
{noformat}

A couple of times, I've gotten lucky and nodetool has provided a more verbose error message:
{noformat}
error: org.apache.cassandra.dht.LocalPartitioner$LocalToken cannot be cast to org.apache.cassandra.dht.ByteOrderedPartitioner$BytesToken
-- StackTrace --

{noformat}

There are 3 nodes in the cluster, and it's using the SimpleStrategy with a 3x replication factor. It's using the ByteOrderedPartitioner (which I know is frowned upon).
