Iyappan Srinivasan commented on MAPREDUCE-753:
----------------------------------------------
Sorry for typo.
In streaming, the "-Dmapred.text.key.partitioner.options" has some options like
"-r -k7,7 -k3,3", which works like this : First sort in the seventh column,
then in that sorting, subsort on 3rd column and reverse both these sorts.
> In Streaming, "comparator options" column does not document the global
> options.
