Andrew Purtell commented on HBASE-12660:
----------------------------------------
bq. For example "hbase.hstore.engine.class".
As the code stands today, we can check the store engine class loadability but
we can't check what it wants wrt. compactor, flusher, or compaction policy
without instantiating it (because how it determines which class to select is
entirely implementation dependent), and we can't do that without creating a
real Store object, because some store components want in their constructors a
Store object for getting configuration. I suppose when the master role is
colocated with regionserver roles that's not so bad. And/or we could spend some
time on making sure we can create instances of configurable plugin classes and
check their health prior to creating an active store.

> As per parent, we do a sanity check for compression, region split policy,
> coprocessors and encryption.
> We should add more checks for the other classes that can be configured
> (either at the RS level or table / CF level). For example
> "hbase.hstore.engine.class".
