Harsh J updated MAPREDUCE-1938:
-------------------------------
Fix Version/s: (was: 0.23.0)
This isn't present in 0.23. Removing from Fix Version. I'll take Arun's word
that it is not needed there either (though it'd look like API breakage, hrm?)
It should be included in 0.22 though.
> Ability for having user's classes take precedence over the system classes for
