Hey Fabian!
Sorry for being unaware regarding Flink configurations, but for me I have
followed every step but still setting a simple cluster of 2 nodes proved to
be a pain in the as@@#.
So, to which value you think I should set the akka timeout?
Also, in my head the process is the following : S
It's not a requirement but the exception reads "org.apache.flink.runtime.
client.JobClientActorConnectionTimeoutException: Lost connection to the
JobManager.".
So increasing the timeout might help.
Best, Fabian

Hello Fabian!
Thanks for the answer. No I did not. Is this a requirement?

Hi,
did you try to increase the Akka timeout [1]?

Guys seriously I have done the process as described in the documentation of
the standalone cluster 20 times. After I start the cluster with
./start-cluster.sh, I normally see with jps the JobManager process running
in the master and the TaskManager processes running in slaves. Although

The TaskManager cannot reach the JobManager. I get this error. Any ideas?

Hi Michael!
Seems that you were correct. It is weird that I could not set parallelism =
136.
I cannot configure the cluster properly so far. I do everything as it is
described here [1].
It seems that the JobManager is not reachable.

Max

For a cluster that size, having the job manager also be a task manager is not
recommended.

jps is a tool that comes with JDK (see $JAVA_HOME/bin). This is modeled

OK Michael!
I will look into it and will come back at you! Thanks for the help. I agree
that it is quite suspicious the par = 8
Jps? Meaning?
Oh I should mention that the JobManager node is also a TaskManager.

Check that you have slaves and masters set correctly on all machines, and in
particular the one submitting jobs. Make sure that from the machine submitting
the job that it is talking to the correct job manager (jobmanager.rpc.address).
It really sounds like you are some how submitting jobs to
You need to verify your configs are correct. Check that the local machine sees
all the task managers, that is the most likely reason it will reject a higher

without issue on a job with 18 parallelism. I have not used the
No man. I have 17 TaskManagers and each has a number of 8 slots.
Do you think it is better to have 8 TaskManager (1 slot each) ?

Go to the web UI and verify all 136 TaskManagers are visible in the machine you
are submitting the job from. I have encountered issues where not all
TaskManagers start, or you may not have all 17 configured properly to be one
cluster vs 17 clusters of 8.

Hello Flinkers,
I have deployed Flink in a cluster of 17 nodes, each having 8 CPUs. Thus, in
total there are 136 CPUs available.
I have set the parameter askmanager.numberOfTaskSlots = 8 in all machines,
since they have 8 CPUs.
And when I am going to run ./flink run -c classpath jarFile -p 136 a
15 matches
