 Review comment:
   Make sense. Though IllegalArgumentException can be thrown when any part of 
the input table is invalid, a better signature may just be throwing 
CatalogException to conform with that of other existing catalog APIs, since 
we've defined CatalogException's use case as "in case of any runtime exception".
   
   I don't think returning boolean is a good signature as the check can be 
fairly complicated and the caller won't know which part is invalid. Returning 
boolean would be a good option for a single criteria check like "bool 
isTable()".
