Subject [jira] [Commented] (CASSANDRA-8950) NullPointerException in nodetool getendpoints with non-existent keyspace or table
Date Thu, 12 Mar 2015 16:01:38 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-8950?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14358865#comment-14358865
] 

Tyler Hobbs commented on CASSANDRA-8950:
----------------------------------------

Sure, I can review.

Instead of not returning any endpoints, let's print a message about the keyspace (or table)
not existing and return a non-zero exit status.  See the nodetool cfstats behavior in 2.1
for an example.
