[jira] Commented: (CASSANDRA-357) CompareSubcolumnsWith= has no effect

["Jonathan Ellis (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-357?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12741136#action_12741136 ] 

Jonathan Ellis commented on CASSANDRA-357:
------------------------------------------

it looks like your client is returning a result as a hash.  isn't your client's hashing going to screw with the ordering, even if cassandra's is correct?

I'd check the raw thrift results -- I don't see anything obviously wrong on the cassandra code and this is a path that the system tests check.
