Stephan Ewen updated FLINK-1608:
--------------------------------
Description:
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 some non-localhost device.
In cases where the TaskManagers start faster than the JobManager, they pick the
wrong hostname and interface.
The later logic (that tries to connect to the JobManager actor) has a logic
with retries. I think we need a similar logic here...
