When Apache Yetus formed, it started with several key pieces of Hadoop that looked reusable. In addition to our contribution testing infra, the project also stood up a version of our audience annotations for delineating the public facing API[1].
I recently got the Apache HBase community onto the Yetus version of those annotations rather than their internal fork of the Hadoop ones[2]. It wasn't pretty, mostly a lot of blind sed followed by spot checking and reliance on automated tests. What do folks think about making the jump ourselves? I'd be happy to work through things, either as one unreviewable monster or per-module transitions (though a piece-meal approach might complicate our javadoc situation).
