> From StoreFile down to HFile, we currently use a boolean argument for each of the various block cache configuration parameters that exist. The number of parameters is going to continue to increase as we look at compressed cache, delta encoding, and more specific L1/L2 configuration. Every new config currently requires changing many constructors because it introduces a new boolean.
> We should move everything into a single class so that modifications are much less disruptive.
