Steve Loughran commented on HADOOP-10807:
-----------------------------------------
I agree, but need to (maybe) retain the old ones to avoid breaking all that old
code.
There's another issue: does the generic option set need so many that are
MapReduce centric, or could there be an inner one
{{CoreOptionsParser}} that skipped that stuff about setting up jobs
If course, in an ideal world we'd s/GnuOptions/r/jcommander
> GenericOptionsParser needs updating for Hadoop 2.x+
