Summary: Sqoop2: Refactore validations
Key: SQOOP-1439
URL: https://issues.apache.org/jira/browse/SQOOP-1439
Project: Sqoop
Issue Type: Bug
Reporter: Jarek Jarcec Cecho
Assignee: Jarek Jarcec Cecho
Fix For: from/to
On my quest to fix technical depth that I've myself put into Sqoop2, I would
like to propose refactoring validator interface. The problems that I see:
* Validations are *ONLY* server side, client has to always go to the sever to
validate everything. Whereas some validations can never be executed to client,
it would be nice to give client opportunity to run at least some basic
validations.
* Validations are in separate {{Validator}} class and are completely separate
from the actual configuration objects. This makes the development quite hard
and "disconnected".
* Entire interface is very non-intuitive as one has to call methods where
parameters are names of instance variables which is awful and don't provide any
level of checking that you've set validation on the correct object.
I would like to move the validations to annotations so that validation and
given configuration object are in the same place. This will also allow us to
serialize and send them to the client.
