Subject Question about Balancer
Date Thu, 10 Sep 2009 21:50:26 GMT
I currently have an HDFS cluster. On another separate machine (not part of the HDFS cluster
but has the hdfs binaries), I want to run balancer.
The JavaDoc mentions about  dfs.balance.bandwidthPerSec parameter.
Where do I set this? Do I add this into my hdfs-site.xml? Do I have to also add this parameter
in all datanode/namenode? Or do I simply add that on the machine that is going to run the

Suppose, I want a different bandwidthPerSec. Do I have to simply modify the hdfs-site.xml
before running the balancer script?
