Hi all, I have been experiencing memory issue while working with Mahout canopy algorithm on big set of data on Hadoop. I notice that only one reducer was running while other nodes were idle. I was wondering if increasing the number of reduce tasks would ease down the memory usage and speed up procedure. However, I realize that by configuring "mapred.reduce.tasks" on Hadoop has no effect on canopy reduce tasks. It's still running only with one reducer. Now, I'm question if canopy is set that way, or am I not configuring correct on Hadoop?
