Edward Capriolo commented on HIVE-645:
--------------------------------------
Luis,
With any hadoop process setting "mapred.job.tracker=local" runs the map/and
reduce locally in process. So it is not distributed 1 thread for maps,one
thread for reduce. The reason you see more output is because normally the
output map and reduce tasks run on separate nodes. With
"mapred.job.tracker=local" you get all the debug.
