Subject Don't print Ping caused error logs
Date Mon, 19 Jun 2017 09:13:49 GMT
Hi,
Our cluster nodes are behind a SLB(Service Load Balancer) with a VIP and the Cassandra client
access the cluster by the VIP. 
System.log print the below IOException every several seconds. I guess it's the SLB service
which Ping the port 9042 of the Cassandra node periodically and caused the exceptions print.
Any method to prevend the Ping caused exceptions been print?
