Hi all, Given that 3.0-beta1 is already cut, I’d like to call a vote for merging Router-Based Federation (HDFS-10467) to trunk and branch-3.
The vote will run for 7 days as usual. We started the discussion about merging HDFS-10467 a few weeks ago [1] and got good feedback which we’ve incorporated already [2, 3, 4]. There are a couple tasks left: - HDFS-12273 for the UI. This should be completed in the next couple days. - HDFS-12284 for adding security. We can move this for v2 if not completed. We have deployed this in production for 2.7 and we did a few tests with trunk a few months ago. This week, I’m rebasing to trunk (last one was a couple weeks ago) and test trunk in one of our test clusters. Finally, note that all the functionality is in the Router (a new component) so everything is isolated. In addition, no new APIs have been added and we rely fully in ClientProtocol. I’d like to thank the people at Microsoft (specially, Jason, Ricardo, Chris, Subru, Jakob, Carlo and Giovanni), Twitter (Ming and Gera), LinkedIn (Zhe, Erik and Konstantin), and Cloudera (Andrew and Manoj) for the discussion and the ideas. Special thanks to Chris Douglas for the thorough reviews!
