Re: java.net.SocketTimeoutException while Trying to Drop a Collection
There are two times of timeouts. The thrift TimedOutException occurs when the coordinator times out waiting for the CL level nodes to respond. The error is transmitted back to the client and raised. This is a client side socket timeout waiting for the coordinator to respond. See the CassandraHostConfigurator.setCassandraThriftSocketTimeout() setting.

Re: java.net.SocketTimeoutException while Trying to Drop a Collection
Thanks a lot Aaron for the very fast response! I have increased the CassandraThriftSocketTimeout from 5000 to 9000. Is this a reasonable setting? configurator.setCassandraThriftSocketTimeout(9000); Cheers, Christof 2012/5/31 aaron morton aa...@thelastpickle.com There are two times of timeouts.

Re: java.net.SocketTimeoutException while Trying to Drop a Collection
The default value for rpc_timeout is 1 - 10 seconds. You want the socket timeout to be higher than the rpc_timeout otherwise the client will give up before the server.
