----------------------------------
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.
