[jira] [Created] (GIRAPH-693) Giraph-Hive check user code as soon as possible

Nitay Joffe created GIRAPH-693:
----------------------------------

             Summary: Giraph-Hive check user code as soon as possible
                 Key: GIRAPH-693
                 URL: https://issues.apache.org/jira/browse/GIRAPH-693
             Project: Giraph
          Issue Type: Bug
            Reporter: Nitay Joffe
            Assignee: Nitay Joffe


We have a lot of cases of users running long jobs and then failing at the Hive output step because of some misconfigured schema or type mismatch. We'd like to move these errors as soon as possible.
To make this happen I am creating a fake vertex and fake record saver and calling out to user code to write it in checkOutputSpecs (which happens at the beginning). This should catch a lot of user errors early on.
