Todd Lipcon commented on HBASE-1923:
------------------------------------
oops, forgot to write about case where number of reducers is less than the
number of regions. We could either (a) disallow it, or (b) configure the
reducer to simply roll to a new HFile at each region boundary that it crosses.
The load algorithm runs per-hfile, not per-reducer, so should work fine.
I will probably choose option (a) initially :)
