Date Thu, 16 May 2013 19:15:16 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-1421?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13659841#comment-13659841

Hudson commented on ACCUMULO-1421:
----------------------------------

Integrated in Accumulo-1.5-Hadoop-2.0 #120 (See [https://builds.apache.org/job/Accumulo-1.5-Hadoop-2.0/120/])
    ACCUMULO-1421 simplify reflection lookup of SafeModeAction, reverting inadvertent check-in
of LargeRowTest (Revision 1483496)
ACCUMULO-1421 simplify reflection lookup of SafeModeAction (Revision 1483494)
ACCUMULO-1421 fix warnings introduced by previous commits (Revision 1483435)
ACCUMULO-1421 added reflection to improve runtime compatibility between hadoop 1 and 2 JobContext
objects (Revision 1483417)

     Result = SUCCESS

> JobContext switches between an abstract class and an interface in hadoop 1 and 2, causing
runtime compatibility problems in the compiled Accumulo bytecode. Avoid the runtime problem
by using reflection to access the configuration object stored in the JobContext.
