Sreenath Somarajapuram updated TEZ-2795:
----------------------------------------
Description:
Make error handling better
- Currently on error the function returns null, and the callee checks for null
value which is not the best approach.
- Guess the best is to modify the exception to give a meaning full message, and
then re-throw the same. A base try..catch block can be put in to handle all
exceptions.
- Gracefully fail invalid ids - Server shouldn't return error even if ids are
invalid.
