[jira] [Created] (CASSANDRA-6548) Order nodetool ring output by
token when vnodes aren't in use
J.B. Langston created CASSANDRA-6548:
----------------------------------------
Summary: Order nodetool ring output by token when vnodes aren't in use
Key: CASSANDRA-6548
URL: https://issues.apache.org/jira/browse/CASSANDRA-6548
Project: Cassandra
Issue Type: Bug
Reporter: J.B. Langston
It is confusing to order the nodes by hostId in nodetool ring when vnodes aren't in use. This happens in 1.2 when providing a keyspace name:

Among other things, it makes it hard to spot rack imbalances. In the above output, the racks DC1 is actually incorrectly ordered and DC2 is correctly ordered, but it's not obvious until you manually sort the nodes by token.
