------------------------------------------

I traced it back using the nightly builds and it was a while ago (the new tests I am writing
caught it!) and narrowed it down to this set of JIRA's (pls ignore previous list). Seems like
HADOOP-2192 is the obvious one?

HADOOP-2769. TestNNThroughputBnechmark should not use a fixed port for the namenode http port.
 	
HADOOP-2192. Error messages from "dfs mv" command improved. 	
HADOOP-2178.  Job History on DFS. 
HADOOP-2730. HOD documentation update.
HADOOP-2371. Commit for the html/pdf docs.	
HADOOP-2371. Commit for the html/pdf docs.	
HADOOP-2766. Enables setting of HADOOP_OPTS env variable for the hadoop daemons through HOD.
HADOOP-2840. Fix gridmix scripts to correctly invoke the java sort through the proper jar.

exist. This was working before. It will move the file if the user home directory exists.
