Subject [jira] [Commented] (CASSANDRA-7823) IllegalStateException with DROP KEYSPACE IF EXISTS XXX
Date Wed, 10 Sep 2014 22:36:33 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-7823?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14129260#comment-14129260
] 

Tyler Hobbs commented on CASSANDRA-7823:
----------------------------------------

Does this happen consistently for you?  It shouldn't actually get to the point where the error
occurs if the keyspace doesn't exist.
