> Currently, the ability for a core developer to add per-table & per-CF
> configuration settings is very heavyweight. You need to add a reserved
> keyword all the way up the stack & you have to support this variable
> long-term if you're going to expose it explicitly to the user. This has
> ended up with using Configuration.get() a lot because it is lightweight and
> you can tweak settings while you're trying to understand system behavior
> [since there are many config params that may never need to be tuned]. We
> need to add the ability to put & read arbitrary KV settings in the HBase
> schema. Combined with online schema change, this will allow us to safely
> iterate on configuration settings.
