Subject Re: running backup node in the same host as namenode
Date Wed, 11 May 2011 20:06:31 GMT
thanks! this works.
but we need to play a ugly trick.

Is there any way to run the BackupNode
with different config directory?

The current way to start backup node is:
bin/hdfs namenode -backup

But this doesn't provide a way to specify
the config directory.
