-----------------------------------

             Summary: Inconclusive error when TaskManager cannot connect to JobManager
                 Key: FLINK-1351
                 URL: https://issues.apache.org/jira/browse/FLINK-1351
             Project: Flink
          Issue Type: Bug
          Components: JobManager, TaskManager
    Affects Versions: 0.9
            Reporter: Stephan Ewen
            Assignee: Till Rohrmann


The taskmanager currently registers at the jobmanager by resolving the akka URL

{code}
val jobManager = context.actorSelection(jobManagerAkkaURL)
{code}

When the actor lookup fails (actor systems cannot connect), it gives an unspecific timeout message. This is the case when the TaskManager cannot connect to the JobManager.

This should be fixed to give a conclusive error message.
I suggest to add a test where TaskManager is started without JobManager actor system being available.
