Hi Stefano,
Thanks for reporting. I wasn't able to reproduce the problem. I ran
./bin/yarn-session.sh -n 1 -s 2 -jm 2048 -tm 2048 on a Yarn cluster
and it created a Flink cluster with a JobManager and a TaskManager
with two task slots. By the way, if you omit the "-s 2" flag, then the
default is read from the config, which is one task slot.
Could it be that an old TaskManager instance is trying to register
with a new JobManager? It looks like it from the log messages because
the ResourceManager (which creates TaskManagers) is not aware of it.
Still questionable why that instance is lingering around. Could you
try to kill the instance and try bringing up a cluster several times
to see if that solved the problem? If not, could you send me the full
logs to my email address?
Thanks,
Max
