Subject [jira] [Commented] (CASSANDRA-7112) ava.lang.ClassCastException: org.apache.cassandra.db.composites.CompoundComposite cannot be cast to org.apache.cassandra.db.composites.CellName
Date Fri, 02 May 2014 11:15:16 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-7112?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13987599#comment-13987599

Sylvain Lebresne commented on CASSANDRA-7112:
---------------------------------------------

Ok, the super columns problems are not complicated but they are relatively unrelated so I've
created CASSANDRA-7138. Patch here is ready for review.
