Subject Help on decommission
Date Tue, 12 Apr 2011 16:53:31 GMT
I have setup a 4 node cluster for testing. When I setup the cluster, I have setup initial tokens
in such a way that each gets 25% of load and then started the node with autobootstrap=false.



After all nodes are up, I loaded data using the stress test tool with replication factor of
3.  As per of my testing, I am trying to remove one of the node using "nodetool decomission"
but the node seems to be stuck in "leaving" status. 

How do I check whether it is doing any work at all? Please help
