> Hive 0.13 changed the signature of HiveOutputFormat (through commit r1527149) breaking backwards compatibility with previous releases; the return type of getHiveRecordWriter has been changed from RecordWriter to FSRecordWriter.
> FSRecordWriter introduces one new method on top of RecordWriter however it does not extend the previous interface and it lives in a completely new package.
> Thus code running fine on Hive 0.12 breaks on Hive 0.13. After the upgrade, code running on HIve 0.13, will break on anything lower than this.
> This could have easily been avoided by extending the existing interface or introducing a new one that RecordWriter could have extended going forward. By changing the signature, the existing contract (and compatibility) has been voided.
