Till Rohrmann created FLINK-6629:
------------------------------------
Summary: ClusterClient cannot submit jobs to HA cluster if address
not set in configuration
Key: FLINK-6629
URL: https://issues.apache.org/jira/browse/FLINK-6629
Project: Flink
Issue Type: Bug
Components: Client
Affects Versions: 1.2.1, 1.3.0, 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.
