Subject decommissioning nodes help
Date Thu, 08 Jul 2010 23:59:12 GMT
Hi guys
 I am a stuck in my attempt to remove nodes from hdfs.
I followed the steps in https://issues.apache.org/jira/browse/HDFS-1125

a)     add node to dfs.hosts.exclude

b)      dfsadmin -refreshNodes

c)      wait for decom to finish

d)     remove node from both dfs.hosts and dfs.hosts.exclude

But after step a) and b) how do I know if decommission is complete.
I am in the process of decommissioning 6 nodes and don't want to loose any blocks ( rep factor
is 3 ) with a restart.

I also opened https://issues.apache.org/jira/browse/HDFS-1290 if anyone is interested.

Thanks
Arun
