Subject [jira] [Commented] (CASSANDRA-5201) Cassandra/Hadoop does not support current Hadoop releases
Date Fri, 08 Mar 2013 10:36:13 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-5201?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13596999#comment-13596999
] 

Jeremy Hanna commented on CASSANDRA-5201:
-----------------------------------------

I wonder if it would be preferable to have all of the code in tree in the same jar still,
but have different package paths, like org.apache.cassandra.hadoop (for backwards compatibility)
and org.apache.cassandra.hadoop2.  Would that work?
