We have configured 3 node cassandra cluster in RHEL 7.2 version and we are doing cluster testing. When we start cassandra in all 3 nodes they form a cluster and they work fine.
But when we bring one node down using "init 6" or "reboot" command, the rebooted node takes more time to join the cluster, however if we manually kill and start cassandra process the nodes join cluster immediately without any issues. We have provided all 3 IPs as seed nodes and the cluster name is same for all 3 nodes and their respective IP as listen address. Selinux is also disabled. Please help us in resolving this issue. Thanks
