Hi I'm running Cassandra 2.1.5 ,(single datacenter ,4 node,16GB vps each
node ),I have given my configuration below, I'm using python driver on my
clients ,when i tried to insert  1049067 items I got an error.

cassandra.WriteTimeout: code=1100 [Coordinator node timed out waiting for
replica nodes' responses] message="Operation timed out - received only 0
responses." info={'received_responses': 0, 'required_responses': 1,
'consistency': 'ONE'}

also I'm getting an error when I check the count of CF from cqlsh

OperationTimedOut: errors={}, last_host=127.0.0.1

I've installed Datastax Ops center for monitoring  nodes , it shows about
1000/sec write request even the cluster is idle .

Is there any problem with my cassandra configuration
