Subject [jira] Commented: (ZOOKEEPER-127) Use of non-standard election ports in config breaks services
Date Fri, 03 Oct 2008 13:26:44 GMT

    [ https://issues.apache.org/jira/browse/ZOOKEEPER-127?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12636633#action_12636633
] 

Patrick Hunt commented on ZOOKEEPER-127:
----------------------------------------

are there tests for these cases?

host:port and host:port:port? we should verify both cases (even if one is illegal - verify
handled appropriately)

> In QuorumCnxManager.toSend there is a call to create a connection as follows:
>     channel = SocketChannel.open(new InetSocketAddress(addr, port));
> Unfortunately "addr" is the ip address of a remote server while "port" is the electionPort
of *this* server.
> As an example, given this configuration (taken from my zoo.cfg)
>   server.1=10.20.9.254:2881
>   server.2=10.20.9.9:2882
>   server.3=10.20.9.254:2883
> Server 3 was observed trying to make a connection to host 10.20.9.9 on port 2883 and
obviously failing.
> In tests where all machines use the same electionPort this bug would not manifest itself.
