Subject Re: Error: Unexpected -D while processing...

Removing the -D is the right thing to do.  The warning re:
GenericOptionsParser can be safely ignored.

If you want more info about the warning to put your mind at ease, take a look at
src/mapred/org/apache/hadoop/mapred/JobClient.java (line 1550 for
context on the warning)
src/core/org/apache/hadoop/util/Tool.java (for the Tool interface)
