Hello hadoop developers, I just opened two jiras proposing to introduce ConsensusNode into HDFS and a Coordination Engine into Hadoop Common. The latter should benefit HDFS and HBase as well as potentially other projects. See HDFS-6469 and HADOOP-10641 for details. The effort is based on the system we built at Wandisco with my colleagues, who are glad to contribute it to Apache, as quite a few people in the community expressed interest in this ideas and their potential applications.
We should probably keep technical discussions in the jiras. Here on the dev list I wanted to touch-base on any logistic issues / questions. - First of all, any ideas and help are very much welcome. - We would like to set up a meetup to discuss this if people are interested. Hadoop Summit next week may be a potential time-place to meet. Not sure in what form. If not, we can organize one in our San Ramon office later on. - The effort may take a few months depending on the contributors schedules. Would it make sense to open a branch for the ConsensusNode work? - APIs and the implementation of the Coordination Engine should be a fairly independent, so it may be reasonable to add it directly to Hadoop Common trunk. Thanks, --Konstantin
