Resolution: Not A Problem
No longer a problem.
> Flink Job Manager Scheduler & Web Frontend out of sync when Zookeeper is
> unavailable on startup
> -----------------------------------------------------------------------------------------------
>
> Key: FLINK-7022
> URL: https://issues.apache.org/jira/browse/FLINK-7022
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Coordination
> Affects Versions: 1.2.0, 1.2.1, 1.3.0
> Environment: Kubernetes cluster running:
> * Flink 1.3.0 Job Manager & Task Manager on Java 8u131
> * Zookeeper 3.4.10 cluster with 3 nodes
> Reporter: Scott Kidder
> Priority: Major
>
> h2. Problem
> Flink Job Manager web frontend is permanently unavailable if one or more
> Zookeeper nodes are unresolvable during startup. The job scheduler eventually
> recovers and assigns jobs to task managers, but the web frontend continues to
> respond with an HTTP 503 and the following message:
> {noformat}Service temporarily unavailable due to an ongoing leader election.
> Please refresh.{noformat}
> h2. Expected Behavior
> Once Flink is able to interact with Zookeeper successfully, all aspects of
> the Job Manager (job scheduling & the web frontend) should be available.
> h2. Environment Details
> We're running Flink and Zookeeper in Kubernetes on CoreOS. CoreOS can run in
> a configuration that automatically detects and applies operating system
> updates. We have a Zookeeper node running on the same CoreOS instance as
> Flink. It's possible that the Zookeeper node will not yet be started when the
> Flink components are started. This could cause hostname resolution of the
> Zookeeper nodes to fail.
