> Key: FLINK-6629
> URL: https://issues.apache.org/jira/browse/FLINK-6629
> Project: Flink
> Issue Type: Bug
> Components: Client
> Affects Versions: 1.3.0, 1.2.1, 1.4.0
> Reporter: Till Rohrmann
> Assignee: Till Rohrmann
> Priority: Blocker
> Fix For: 1.3.0, 1.4.0

> In the general case, the {{ClusterClient}} fails to submit jobs to an HA
> cluster. The problem is the {{LazyActorSystemLoader}} which creates an
> {{ActorSystem}}, upon first call. The {{ActorSystem}} is created by reading
> the JobManager's address from the {{Configuration}} in order to find the
> connecting address via {{ConnectionUtils.findConnectingAddress}}. The address
> in the configuration is, however, only valid in the non-HA case. In the HA
> case, we have to obtain the leader's address from ZooKeeper. Therefore, if
> the address is not explicitly set in the {{flink-conf.yaml}}, then the
> {{ClusterClient}} might either fail with a {{RuntimeException}} if no address
> at all has been specified or it will use an invalid address and retrieve the
> wrong connecting address.
