I frequently run small versions of my Hadoop jobs as local single machine jobs to debug my logic. When I do this I always get only a single reduce task even when I call setNumReduceTasks with, say 10.
I want to debug some issues with the number of reducers and wonder if there is a way to force local hadoop jobs to emulate multiple reduce tasks -- Steven M. Lewis PhD 4221 105th Ave Ne Kirkland, WA 98033 206-384-1340 (cell) Institute for Systems Biology Seattle WA
