title: Flink HA Cluster JobManager issues
body: <p>I have a setup with flink 1.2 cluster, made up of 3 JobManagers and 2 TaskManagers. I start the Zookeeper Quorum from JobManager1, I get confirmation Zookeeper starts on the other 2 JobManagers then I start a Flink job on this JobManager1.   </p>
  
  <p>The flink-conf.yaml is the same on all 5 VMs this means jobmanager.rpc.address: points to JobManager1 everywhere.</p>
  
  <p>If I turn off the VM running JobManager1 I would expect Zookeeper to say one of the remaining JobManagers is the leader and the TaskManagers should reconnect to it. Instead I get in the TaskManagers' logs a lot of these messages </p>

  <p>I modified the original IP to 1.2.3.4 for confidentiality and because it's always the same IP (of JobManager1).</p>

  <p>Does anyone know why the TaskManagers are not trying to reconnect to one of the remaining JobManagers (like 1.2.3.5 above)?</p>
  
  <p>Thanks!</p>
