Hey all, Earlier this year, Facebook released a bunch of its code browsing/review tools as a new (and independent) open source project called Phabricator:
http://phabricator.org/ We're currently experimenting with using it for improving the developer experience when contributing and reviewing Hive and HBase patches. (Also for eliminating committer confusion from different patch versions submitted to Review Board and JIRA, something which has bitten us a few times already.) You may notice some of this activity showing up in JIRA, e.g. https://issues.apache.org/jira/browse/HIVE-2515 I'll be sending out a lot more info once we've finished some of the setup and validation, but I just wanted to send out a heads-up for those who are already familiar with using the existing Review Board setup. Once validation is done, we'll publish instructions so that everyone can test it out for themselves as a potential alternative to Review Board. JVS
