Cluster execution - Jobmanager unreachable
Hello,
I'm trying to run python jobs with the latest master on a cluster and
get the following exception:
Error: The program execution failed: JobManager not reachable anymore.
Terminate waiting for job answer.
org.apache.flink.client.program.ProgramInvocationException: The program
execution failed: JobManager not reachable anymore. Terminate waiting
for job answer.

Re: Cluster execution - Jobmanager unreachable
Posted by Till Rohrmann <ti...@gmail.com>.
I found the error. Due to some refactoring, a wrong message was sent to the
JobManager in the JobManagerInfoServlet.java. I pushed a fix. Could you try
it out again?

Re: Cluster execution - Jobmanager unreachable
Posted by Till Rohrmann <ti...@gmail.com>.
Could you check the rebasing because it seems as if the web server is now
sending RequestArchivedJobs messages to the JobManager which should not
happen. These messages should go directly to the MemoryArchivist. The
corresponding file is JobManagerInfoServlet.java, I think.

Re: Cluster execution - Jobmanager unreachable
Posted by Chesnay Schepler <ch...@fu-berlin.de>.
I just tried Till's fix, rebased to the latest master and got a whole

java.lang.Exception: The slot in which the task was scheduled has been
killed (probably loss of TaskManager).

Re: Cluster execution - Jobmanager unreachable
Posted by Till Rohrmann <tr...@apache.org>.
I checked and indeed the scheduleOrUpdateConsumers method can throw an
IllegalStateException without properly handling such an exception on the
JobManager level.
It is a design decision of Scala not to complain about unhandled exceptions
which are otherwise properly annotated in Java code. We should definitely
pay attention in Scala to properly handle thrown exceptions of Java code.

Re: Cluster execution - Jobmanager unreachable
Posted by Ufuk Celebi <uc...@apache.org>.
Chesnay, could you try this again with Till's fix: https://github.com/apache/flink/pull/378
The changes look good and I would like to merge it asap, but it would be nice to double check with your problem. I will also run some tests.

I suspect that this is one of the cases where an exception in an actor
causes the actor to die (here the job manager)

Re: Cluster execution - Jobmanager unreachable
Posted by Till Rohrmann <tr...@apache.org>.
It looks to me that the TaskManager does not receive a
ConsumerNotificationResult after having send the ScheduleOrUpdateConsumers
message. This can either mean that something went wrong in
ExecutionGraph.scheduleOrUpdateConsumers method or the connection was
disassociated for some reasons. The logs would indeed be very helpful to
understand what happened.
