Owen O'Malley commented on HADOOP-1977:
---------------------------------------
I looked at this problem. It stems from the fact that JobClient creates a new
JobConf rather than use the Configuration from ToolBase. It would be nice to
have a version of the CLI parsing library that wasn't based on ToolBase and OO
inheritance, since clearly part of what happened here was too much OO magic not
making the required usage clear.
