["Ryan McGuire (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-4191?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13796336#comment-13796336 ] 

Ryan McGuire commented on CASSANDRA-4191:
-----------------------------------------

I just saw this today while testing on EC2 (strangely, I cannot reproduce this locally with ccm):

{code}
$ nodetool status
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0
        at org.apache.cassandra.tools.NodeCmd.main(NodeCmd.java:1123)
{code}

If I specify the keyspace it works fine:

{code}
$ nodetool status system
Datacenter: DC1

{code}

I believe it's due to changes made in this ticket.

> This way cfstats will only print information per keyspace/column family combinations.
> Another related proposal as an alternative to this ticket:
> Allow for `nodetool cfstats` to use --excludes or --includes to accept keyspace and column family arguments.
