Chris Donati created CASSANDRA-12942:
----------------------------------------
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 --
java.lang.ClassCastException:
org.apache.cassandra.dht.LocalPartitioner$LocalToken cannot be cast to
org.apache.cassandra.dht.ByteOrderedPartitioner$BytesToken

{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).
