> Before doing the more significant changes to HMaster, it would benefit
> greatly from some cleanup, commenting, and a bit of refactoring.
> One motivation is to nail down the initialization flow and comment each step.
> Another is to add a couple new classes to break up functionality into
> helpers to reduce HMaster size (for example, pushing all filesystem
> operations into their own class). And lastly to stop the practice of passing
> around references to HMaster everywhere and instead pass along only what is
> necessary.
