Description
The following query will break Qserv:
SELECT objectId, objectId as o1.objectId FROM Object LIMIT 1
|
ERROR 4005 (Proxy) at line 1: Cannot connect to Qserv master;
|
Exception in RPC call: ...tack/Linux64/lua/5.1.4/share/lua/5.1/xmlrpc/http.lua:41:
|
connection refused
|
Here is what vanilla MySQL does:
ERROR 1064 (42000) at line 1: You have an error in your SQL syntax; check the manual
|
that corresponds to your MySQL server version for the right syntax to use near
|
'.objectId FROM Object LIMIT 1' at line 1

This appears to no longer crash Qserv, but returns a generic ParseException. It would still be good to improve the error message with at least an indication of where the parse failed.
