+1 LGTM, ran full build with unit tests and tried Ambari Format as well as
Record Format with an AvroRecordSetWriter. Verified the records are in the
prescribed format and the standard S2S reporting task attributes are correct.
Also the documentation is great, thanks for this addition! Merging to master---
