Jongyoul Lee commented on YARN-6771:
------------------------------------
It's related to classloader and its usage. To make a test case, we need class
that is not included in default class loader it means we need to make a class
in order not to be included when running test. I'm not sure what the best way
is, but one possible way is to make a class dynamically when starting test. May
I use that way to test it?

> While running {{RpcClientFactoryPBImpl.getClient}},
> {{RpcClientFactoryPBImpl}} uses {{localConf.getClassByName}}. But in case of
> using custom classloader, we have to use {{conf.getClassByName}} because
> custom classloader is already stored in {{Configuration}} class.
