Bikas Saha commented on YARN-149: --------------------------------- I will be posting a short design/road-map document shortly. If anyone has ideas, notes etc. then please start posting so that I can consolidate them. Overall, most of the tools and interfaces are already available in common via the HDFS HA project. The work will mainly be around integrating them with YARN/RM. > ResourceManager (RM) High-Availability (HA) > ------------------------------------------- > > Key: YARN-149 > URL: https://issues.apache.org/jira/browse/YARN-149 > Project: Hadoop YARN > Issue Type: New Feature > Reporter: Harsh J > Assignee: Bikas Saha > > One of the goals presented on MAPREDUCE-279 was to have high availability. > One way that was discussed, per Mahadev/others on > https://issues.apache.org/jira/browse/MAPREDUCE-2648 and other places, was ZK: > {quote} > Am not sure, if you already know about the MR-279 branch (the next version of > MR framework).
