Subject [jira] [Commented] (HADOOP-8501) Gridmix fails to compile on OpenJDK7u4
Date Tue, 12 Jun 2012 16:58:43 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8501?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13293766#comment-13293766
] 

Thomas Graves commented on HADOOP-8501:
---------------------------------------

+1 change looks good to make it compile. I would recommend using trunk or branch-2 if you
are actually going to run gridmix as there are jiras not pulled into 0.23.
