I installed latest nightly build and it seems that my nutch is finally stable, however i was wondering about one thing running reduce tasks are showing something like: reduce > copy (54 of 153 at 0.00 MB/s) why is it 0.00 MB/s ? sometimes i get 0.01 or 0.02 but it's still very slow. Is that normal or is this caused by some bad configuration ? I'm using a large number of maps (150) and 9 reduce jobs on a cluster of 3 machines. I tried lowering those, but i kept on getting memory problems. Could it be caused by small amount of data in each of map tasks ?
