Review Comment:
   I would expect modifyProperties to throw TableNotFoundException. At least, 
some error should happen if the table doesn't exist... I'm not sure what error 
that is. But, I think this PR should wait until we figure that out, because 
this changes the behavior, and we shouldn't change the API behavior for the 
case when the table doesn't exist.
