Review comment:
You don't want to do get
return ChecksymType.nameToType(conf.get(HConstants.CHECKSUM_TYPE_NAME,
DEFAULT_WHATEVER_IT_IS));
Is this a candidate for StoreContext? (Perhaps if called frequently).
Perhaps StoreContext is not available where this is used?

Review comment:
Yeah, just trying to understand why. You want to swap out the HStore
implementation or something?

Review comment:
Why introduce an StoreContext? Isn't that what a Store is? Store spans
files.
(We need the 'H' in HStoreContext?)
