Cameron McKenzie commented on CURATOR-411:
------------------------------------------
Can someone explain the testNewMembers() test to me, maybe I'm missing
something:
>From my reading, a cluster with 5 instances is created, but only 3 of them are
>started.
The Curator client is created knowing only about the 3 instances that are
started. When it connects to the cluster it queries the configuration of the
cluster and finds that there are 5 instances. This much of the test works OK.
The next bit is what seems strange to me. It does a reconfig call to ZK
withNewMembers, but passes in the existing 3 instances that the client already
knows about. This seems to cause problems because ZK tries to open a server
socket on the ports defined in the new connection string, but they are already
present. See below:
ERROR org.apache.zookeeper.server.NIOServerCnxnFactory Error reconfiguring
client port to /0.0.0.0:35841 Address already in use
[LearnerHandler-/127.0.0.1:47224]
ERROR org.apache.zookeeper.server.quorum.QuorumCnxManager Exception while
listening [/0.0.0.0:42569]

org.apache.zookeeper.server.quorum.QuorumCnxManager$Listener.run(QuorumCnxManager.java:638)
I don't understand what this part of the test is meant to be doing. If it's
trying to add new members, shouldn't it be binding new ports in the connection
string being passed to withNewMembers()?
