> YARN-10838 introduced a ConfigurationProperties class, that is optimised for
> fast prefixed retrievals. However, changes at runtime on a CSConfig object
> will not have effect on this cache. The only way to propagate those changes
> is to reinitialise the entire cache, which could be costly.
> In order to avoid unnecessary operations, we need a way to add new entries to
> the ConfigurationProperties in constant time.
> In addition to this, YARN-11006 implemented a way for dynamic queues to be
> able to override user limit factors via templates. However, this only worked
> because of the missing propagations, hence it is a bug in the logic that
> should be fixed.
