Hi,
I has this problem before, and in my case it is because the
executor/container was killed by yarn when it used more memory than
allocated. You can check if your case is the same by checking yarn node
manager log.
Best,
Patcharee

Is this a problem with my code or the cluster ? Is there any way to
fix it ?
