Subject [VOTE] Merge Router-Based Federation (HDFS-10467) branch into trunk/branch-3
Date Fri, 29 Sep 2017 18:58:56 GMT
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!



Regards,
Inigo
