Subject RE: [Reduce task stalls] Problem Detailed Report
Date Thu, 08 May 2008 21:57:51 GMT
Hi,
I had similar symptoms when one of my slave /etc/hosts entry was wrong.

Few suggestions:
-- Check the output of "start-dfs.sh" and make sure the host names or 
ip addrs are correct for all the nodes
-- Run  bin/hadoop fsck "/"  and make sure the file system is healthy.

thanks,
Mohan
