Check the nodetool executable, it's a shell script, and try echoing the CLASSPATH in there and check it correctly point to what it should. -- Sylvain On Thu, Nov 1, 2012 at 9:10 AM, Brian Fleming bigbrianflem

Hi, We simulated a node 'failure' on one of our nodes by deleting the entire Cassandra installation directory reconfiguring a fresh instance with the same token. When we issued a 'repair' it started streaming data back onto the node as expected. However after the repair completed, we had over

Efficiency of Cross Data Center Replication...?
