Note that related failure has been fixed in YARN-9813. We can hopefully use a
similar approach here.

I made some investigation, but don't have a proposed solutions to this.
Some related articles and stuff:
- It is a known [migration
problem|https://blog.codefx.org/java/java-9-migration-guide/#Casting-To-URL-Class-Loader]
from Java 8 to 9. This article says some case where the migration is easy, but
non of them is applicable here.
- The [Oracle community|https://community.oracle.com/thread/4011800] has also
got a thread about this problem, might worth chasing that option they suggested.
Most likely it is just a testing issue, but I am still unsure about this.
I'm also CC [~billie.rinaldi], as had some work around this area. If you have
any thoughts on this, we'd be happy.
Also other components bumped into this - similar: TEZ-3860.
