Review comment:
       This is a summary sheet of raw exceptions thrown in Catalyst of 
branch-3.0: [OSS Catalyst Exception Messages: 
Branch-3.0](https://docs.google.com/spreadsheets/d/10HmOs-RIRaur2b_zLuOpRXC2b45KfpHwTBpQyalTV-s/edit?usp=sharing).
 Apart from `AnalysisException` and its sub-exceptions, there are a lot of 
other exceptions, for example, `IllegalArgumentException` and 
`UnsupportedOperationException`.  
   
   We generally have two ways to group these messages:
   * By component. All messages from a single components, no matter the 
exception type, are grouped into one exception file.
   * By exception type. All messages of a single exception type are created in 
the corresponding exception object. It is great because by calling 
`AnalysisException.groupingIDMismatchError` we know the exception type this 
function throws. But this approach has a problem: those Java/Scala internal 
exception type cannot follow this way. 
   
   Due to the small problem of the latter one, I choose the first one of 
grouping all exception messages from Catalyst in one file. Or do you have any 
thoughts on that? Thanks!
