ZOOKEEPER-2836 fix SocketTimeoutException
----
> QuorumCnxManager.Listener Thread Better handling of SocketTimeoutException
> --------------------------------------------------------------------------
>
> Key: ZOOKEEPER-2836
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2836
> Project: ZooKeeper
> Issue Type: Bug
> Components: leaderElection, quorum
> Affects Versions: 3.4.6
> Environment: Machine: Linux 3.2.0-4-amd64 #1 SMP Debian 3.2.78-1
> x86_64 GNU/Linux
> Java Version: jdk64/jdk1.8.0_40
> zookeeper version: 3.4.6.2.3.2.0-2950
> Reporter: Amarjeet Singh
> Priority: Critical
>
> QuorumCnxManager Listener thread blocks SocketServer on accept but we are
> getting SocketTimeoutException on our boxes after 49days 17 hours . As per
> current code there is a 3 times retry and after that it says "_As I'm leaving
> the listener thread, I won't be able to participate in leader election any
> longer: $<hostname>/$<ip>:3888__" , Once server nodes reache this state and
> we restart or add a new node ,it fails to join cluster and logs 'WARN
> QuorumPeer<myid=1>/0:0:0:0:0:0:0:0:2181:QuorumCnxManager@383 - Cannot open
> channel to 3 at election address $<hostname>/$<ip>:3888' .
> As there is no timeout specified for ServerSocket it should never
> timeout but there are some already discussed issues where people have seen
> this issue and added checks for SocketTimeoutException explicitly like
> https://issues.apache.org/jira/browse/KARAF-3325 .
> I think we need to handle SocketTimeoutException on similar lines for
> zookeeper as well
