Edward Capriolo commented on HIVE-795:
--------------------------------------

I think this is good. Often times when returning an int status a composite 
object with status message is better. Someone recently issued a similar request 
for HWI on hive-user. So I look forward to this one. 

> Return better error messaging from HiveServer

> If an exception is thrown on the Hive server (i.e., when an invalid query is 
> passed), the Hive server throws a HiveServerExcpeption to the client with a 
> message like "Query returned non-zero code: 10". A more informative 
> description of the cause of the error should be returned.
