Subject [jira] [Commented] (CASSANDRA-4687) Exception: DecoratedKey(xxx, yyy) != DecoratedKey(zzz, kkk)
Date Thu, 09 Jan 2014 16:59:18 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-4687?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13866798#comment-13866798

Jacek Furmankiewicz commented on CASSANDRA-4687:
------------------------------------------------

Sorry, somewhat confused here on that last statement.

The patch that we applied seemed to have fixed the DecoratedKey issue, but introduced the
seek issue instead.
So how can it be the same thing? Is it just a bug in the custom patch?
