The object 'account_master' belongs to user1 (assume). Now update privs on 'account_master' is to be granted to database user or role 'stage', by user1.

This fails as the database into which you are importing this dump file does not have an user or role called 'stage'. Thats it!

So, create an user or role called 'stage' (as per your requirement) to handle this error.

HTH.
