Hi, I set up a 2-node Hadoop cluster, whose nodes are all in the same network and ran the 'grep' example. The map tasks were distributed among the two machines and ran without any problem. However, the reduce task, which is running at the slave node, doesn't seem to finish and stops at 11%. I checked the reduce task tracker and it shows the following message:
reduce > copy (5 of 15 at 0.00 MB/s) > Can anyone let me know where the problem comes from? and how to fix it? I really appreciate it! Thank you, Ming Yang
