I have a 3 node Cassandra Cluster. Using DataStax Enetrprise v4.5.1 on VMWare.
I am adding 1 new node to this cluster for running Analytics workload.
So I cloned existing one of the Cassandra VMs, changed the hostname, restarted
VMs, then updated Cassandra.yaml file and restarted Cassandra.
172.17.3.1 - Cassandra Node
172.17.0.173 - Analytics Node, cloned from above node.
Now when this new node join the cluster, the existing node seem to disappear.
I thought it is the issue with tokens, so I moved the new node to a new token,
still the same problem.
In the log files I see:
INFO [HANDSHAKE-/172.17.3.1] 2014-08-08 11:59:18,847 OutboundTcpConnection.java
(line 386) Handshaking version with /172.17.3.1
INFO [GossipStage:1] 2014-08-08 11:59:19,094 Gossiper.java (line 910) Node
/172.17.3.1 is now part of the cluster
WARN [GossipStage:1] 2014-08-08 11:59:19,100 StorageService.java (line 1572)
Not updating host ID 3ce2cc13-7a3c-45cf-9a14-b29b0b7cfb4e for /172.17.3.1
because it's mine
When checked through nodetool on the new node, it shows only three nodes,
172.17.3.1 is not showing up.
