[jira] Commented: (HADOOP-364) rpc versioning broke out-of-order server launches

    [ http://issues.apache.org/jira/browse/HADOOP-364?page=comments#action_12421277 ] 
            
Owen O'Malley commented on HADOOP-364:
--------------------------------------

The patch also extends the mini-mr cluster and mini-dfs cluster classes to take a boolean on the constructor saying to bring up the datanode/tasktracker first. I changed one of the junit tests to bring up the servers backwards to make sure that the fix works.
