I'm trying to re balance my cluster as I've added to more nodes.
When I run balancer with the default threshold I am seeing timeouts in
the logs:

2008-07-18 09:50:46,636 INFO org.apache.hadoop.dfs.Balancer: Decided to
move block -8432927406854991437 with a length of 128 MB bytes from
10.11.6.234:50010 to 10.11.6.235:50010 using proxy source 10.11.6.234:50010

2008-07-18 09:52:46,826 WARN org.apache.hadoop.dfs.Balancer: Timeout
moving block -8432927406854991437 from 10.11.6.234:50010 to
10.11.6.235:50010 through 10.11.6.234:50010

I read in the balancer guide->
http://issues.apache.org/jira/secure/attachment/12370966/BalancerUserGuide2
That the default transfer rate is 1mb/sec
I tried increasing this to 1gb/sec but I'm still seeing the timeouts.
All of the nodes have gigE nics and are on the same switch.
