[jira] [Commented] (GORA-76) Upgrade to Hadoop 1.0.0

["Lewis John McGibbney (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GORA-76?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13247183#comment-13247183 ] 

Lewis John McGibbney commented on GORA-76:
------------------------------------------

Hi Ferdy, I'm with you on this one. I can replicate absolutely everything you've posted above. If you look at your log output, the code fails at line 148 on HadoopTestCase [0]. This is because 
javax.management.InstanceAlreadyExistsException: MXBean already registered with name Hadoop:service=NameNode,name=MetricsSystem,sub=Control

I'll look into it, but right now I need help from elsewhere to find out why this is the case.
