Richard updated SQOOP-2266:
---------------------------
    Description: When the client receives the response with throwable bean from 
the server, it will try to reflect the exception class. However, it the 
{{ErrorCode}} class is in {{sqoop-core}} or other module instead of 
{{sqoop-common}}, {{NPE}} will be throw (SQOOP-2054). So [~abec] and me moved 
all {{ErrorCode}} into {{sqoop-core}} (SQOOP-2054, SQOOP-2172). And [~jarcec] 
fixed {{NPE}} with avoid throwing exception (SQOOP-2225), then moved several 
{{ErrorCode}} back to their own module (SQOOP-2248, SQOOP-2249, SQOOP-2251 and 
SQOOP-2247). But this solution does not solve   (was: When the client receives
