Description

There is currently only one concrete FaultDomainManager implementation, and it is for YARN usage. It is also specified as the default in code. However, for non-YARN environments, we shouldn't include YARN dependencies, so we need another concrete implementation. For now, we can just add a very simple implementation as a placeholder.
