Subject Using a node in separate cluster without decommissioning.
Date Tue, 10 Jul 2012 18:35:15 GMT

I want to take out 2 nodes from a 8 node cluster and use in another
cluster, but can't afford the overhead of streaming the data and
rebalance cluster. Since replication factor is 2 in first cluster, I
won't lose any data.

I'm planning to save my commit_log and data directories and
bootstrapping the node in the second cluster. Afterwards I'll just
replace both the directories and join the node back to the original
cluster.  This should work since cassandra saves all the cluster and
schema info in the system keyspace.

Is it advisable and safe to go ahead?
