I think for new tables it is reasonable to check known schema options that require classes to be available on the server side when processing the admin request RPC, and throw an exception back if we can't find it.

For existing tables, do we check if classes in schema options are still reachable and refuse deployment instead of aborting? I don't know. Something is seriously wrong with the RS environment.

> When processing table create and modification requests we should check the supplied schema options for settings that require mentioned classes to be available from the regionserver classpath (split policies, etc.). If we can't find the class on the classpath when processing the admin request RPC, fail the operation immediately and return an exception rather than allow problems later, such as aborts.
