----------------------------------
We ran into a timeout because of the YARN Session cluster's

[...] {code}
This {{join}} command should have gotten back due to {{sendStop}} call that was
triggered beforehand.
I have to do another round to double-check but I guess the stop call never
reached the thread because the previous failure of the job submission Runner
resetted the System input/output streams which cut off the communication
between the {{main}} and the YARN Session Cluster Thread as well.
