Subject No zero ( 2 ) exit code on k8s StandaloneJobClusterEntryPoint when save point with cancel...
Date Tue, 23 Apr 2019 17:59:13 GMT
I am seeing this weird issue where I do a save point with cancel on a job
on k8s and it hangs for 5 minutes ( no INFO logs ) and then exits with code
of 2.

and after 5 minutes ..

In the interim, I get this at a regular clip

Any ideas as to whether it is this inability to shut down the Worker that
is causing this issue ?
