Review Comment:
   I completely agree we need to have our own family of exceptions, but I think 
it will need more discussion.
   
   My initial suggestion is to reserve `PinotRuntimeException` name for a 
marker exception that extends `RuntimeException`, then add another for queries 
(something like `QueryException`) and then

           +column
       }
       note for ColumnExecutionQException "Execution exception dealing with a 
column"
   ```
