Subject Re: rack topology data update
Date Thu, 13 Sep 2012 05:51:15 GMT
Hi harsh,

I have followed your suggestion operation.

1, stop the new datanode.(I have modified the topology file in the namenode
before.)
2, run 'hadoop dfsadmin -refreshNodes' on the namenode
3, start the new datanode.

But it really not update the new topology mapping.
It just show the start info in the namenode that:
"
2012-09-13 13:44:14,706 INFO org.apache.hadoop.net.NetworkTopology:
Removing a node: /default-rack/10.0.10.100:50010
2012-09-13 13:44:14,706 INFO org.apache.hadoop.net.NetworkTopology: Adding

"
