      Description

      FPG advertises that numgroups will default to 1000, but it actually uses 50. If you do not override the default, only 50 reducers get work even if you have many more.

        Changes the default to be 1000, generate default message using same static var as used for default, adjust default to be "1000 or at least number of reducers".
