Chesnay Schepler commented on FLINK-4152:
-----------------------------------------
it looks like the Registration is restarted several times. You can see a lot of
info messages where attempt=1.
{code}
2016-07-05 09:57:30,126 INFO org.apache.flink.yarn.YarnTaskManager - Trying to
register at JobManager akka.tcp://flink@10.240.0.5:56147/user/jobmanager
(attempt 1, timeout: 500 milliseconds)
{code}
The backoff for the following attempts does seem to work.
> TaskManager registration exponential backoff doesn't work

>
> While testing Flink 1.1 I've found that the TaskManagers are logging many
> messages when registering at the JobManager.
> This is the log file:
> https://gist.github.com/rmetzger/0cebe0419cdef4507b1e8a42e33ef294
> Its logging more than 3000 messages in less than a minute. I don't think that
> this is the expected behavior.
