Subject Re: nodetool move trying to stream data to node no longer in cluster
Date Thu, 26 May 2011 07:10:22 GMT
cool. I was going to suggest that but as you already had the move running I thought it may
be a little drastic. 

Did it show any progress ? If the IP address is not responding there should have been some
sort of error. 

Cheers

IPs.
