Can you post the rest of that stack trace?
Yes, here are 2 stack traces that were encountered. We basically had
the cluster working for a few years. We introduced a new Valve for
authentication purposes. Also, with this change we had to set a proxy
in CATALINA_OPTS, I'm not sure if that affected local communication
between the nodes? For now we commented out the cluster on each of
our nodes in order to have it running.

Hmm... no "caused by"? That's disappointing. NCDFE usually means "you
done broke your install" but it says that the initialization of the
class failed, not that the class wasn't actually found.
Any way you can attach a debugger and find out what's causing that to be
thrown?
What was your previous version of Tomcat?
We were always on version 9. We keep it pretty much up to date with
the latest available. I am not sure of the sub-version we started at
where it was working. I'm guessing it was whatever version was the
latest around Jan-2019.
Did you upgrade all nodes at the same time, or are you upgrading a single node
in the cluster?
All are at the same version, we have 4, they all get updated at the same time.
How did you upgrade (e.g. installer, unzip/untar/etc.)?
untar
Yeah, that definitely smells weird. I have no specific advice (other
than "try a debugger") but I do want to at least validate that it
doesn't look like you are doing anything wrong, or misinterpreting
something obvious :)
