Subject Re: running backup node in the same host as namenode
Date Tue, 10 May 2011 01:33:33 GMT
Since they are using different ports, I donot think there will be a problem. Only problem can
arise because of namespace directory. I did not tested but should work in following steps:
1- Start NameNode.
2- change dfs.name.dir in hdfs-site.xml
3- start BackupNode

Subject: running backup node in the same host as namenode

hi all,

I am using hdfs 0.21.0, and want to run
Backup Node in the same host as the NameNode
for experiment purpose.

Can anyone shed some light on how to do that?

Many thanks,
Thanh
