With 2.7.0 out of the way, and with more maintenance releases to stabilize it, I propose we start thinking about 2.8.0.
Here's my first cut of the proposal, will update the Roadmap wiki. - Support *both* JDK7 and JDK8 runtimes: HADOOP-11090 - Compatibility tools to catch backwards, forwards compatibility issues at patch submission, release times. Some of it is captured at YARN-3292. This also involves resurrecting jdiff (HADOOP-11776/YARN-3426/MAPREDUCE-6310) and/or investing in new tools. - HADOOP-11656 Classpath isolation for downstream clients - Support for Erasure Codes in HDFS HDFS-7285 - Early work for disk and network isolation in YARN: YARN-2139, YARN-2140 - YARN Timeline Service Next generation: YARN-2928. At least branch-merge + early peek. - Supporting non-exclusive node-labels: YARN-3214 I'm experimenting with more agile 2.7.x releases and would like to continue the same by volunteering as the RM for 2.8.x too. Given the long time we took with 2.7.0, the timeline I am looking at is 8-12 weeks. We can pick as many features as they finish along and make a more predictable releases instead of holding up releases for ever. Thoughts? Thanks +Vinod
