Hi, I am implementing my own serde and storage handler. Is there any method in one of these interfaces (or any other) which give me a handle to do some operation after all the records have been written by all reducer. Something very similar to job level output committer. I want to update some state in an external system once I know job has completed successfully. Ideally, I would do this kind of a thing in a job level output committer, but since Hive is on old MR api, I dont have access to that. There is a Hive's RecordWriter#close() I tried that but it looks like its a task level handle. So, every reducer will try to update the state of my external system, which is not I want. Any pointers on how to achieve this will be much appreciated. If its unclear what I am asking for, let me know and I will provide more details.
Thanks, Ashutosh
