Hi,
I have added new nodes to an existing cluster and ran the “nodetool cleanup”. I

java.util.concurrent.ExecutionException
the whole gc_grace thing will eventually
go away, eg by modifying C* to only drop known repaired tombstones.

Thanks.

Hi Gudmundur, each write and overwrite has a timestamp associated with it (you

provided by the Cassandra server if you don't explicitly supply it yourself

Hi Peter, are you using the hsha RPC server type on this node? If you are, then
it looks like rpc_max_threads threads will be allocated on startup in 2.0.11
while this wasn't the case before. This can exhaust your heap if the value of
rpc_max_threads is too large (eg if you use the default).

Hi Kevin, if you are using the latest version of opscenter, then even the

pretty convenient.
