[jira] [Created] (FLINK-1608) TaskManagers may pick wrong network interface when starting before JobManager

Stephan Ewen created FLINK-1608:
-----------------------------------

             Summary: TaskManagers may pick wrong network interface when starting before JobManager
                 Key: FLINK-1608
                 URL: https://issues.apache.org/jira/browse/FLINK-1608
             Project: Flink
          Issue Type: Bug
          Components: TaskManager
    Affects Versions: 0.9
            Reporter: Stephan Ewen
             Fix For: 0.9


The taskmanagers use a NetUtils routine to find an interface that lets them talk to the Jobmanager. However, if the JobManager is not online yet, they fall back to localhost.

In cases where the TaskManagers start faster than the JobManager, they pick the wrong hostname and interface.
