Hi @cxzl25, thanks for tackling this race condition! The fix looks
reasonable.
I'm still understanding the History Server caching architecture. A few
questions:
1. Is there a risk of the `diskManager.foreach(_.release(...))` call
racing with a concurrent `getAppUI` request?
2. Should the `synchronized` block be extended to cover the `release` call
as well?
Happy to dig deeper if you can point me to relevant documentation!
