Project: Hadoop
Type: Improvement
Components: mapred
Versions: 0.2
Reporter: Owen O'Malley
Assigned to: Owen O'Malley
Fix For: 0.3

The number of map output server threads in each task tracker is currently set
to the number of task slots. Since the optimum setting depends on the network,
it would be nice to have more threads serving map output files than reduces.
