Subject [jira] [Created] (CASSANDRA-14398) Client TOPOLOGY_CHANGE messages have wrong port.

Greg Bestland created CASSANDRA-14398:
-----------------------------------------

             Summary: Client TOPOLOGY_CHANGE  messages have wrong port.
                 Key: CASSANDRA-14398
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-14398
             Project: Cassandra
          Issue Type: Bug
          Components: Core
            Reporter: Greg Bestland
             Fix For: 4.0.x


Summary:

TOPOLOGY_CHANGE events that are recieved by the client(Driver), with C* 4.0 (Trunk). Contain
the storage port (7000) rather than the native port (9042). I believe this is due to changes
stuck in for CASSANDRA-17544.  

I was able to track it down to this specific call here.
 [https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/service/StorageService.java#L1703

]

We need an accurate port number from this Topology change event, otherwise we won't be able
to correlate node up event against the system.peers_v2 table accurately.

C* version I'm testing against : 4.0.x (trunk)

Steps to reproduce:

1. create a single node, cluster, in this case I'm using ccm.
{code:java}
ccm create 400-1 --install-dir=/Users/gregbestland/git/cassandra
ccm populate -n 1
ccm start
{code}
2. Connect the java driver, and check metadata.
 see that there is one node with the correct native port (9042).

3. Add a brand new node:
{code:java}
ccm add node2 -i 127.0.0.2
ccm node2 start
{code}
4. Incoming topology change message to client will have the storage port, rather then the
native port in the message.
