Re: [VOTE] Merge HDFS-5535 Rolling Upgrade Improvement

+1 for merging. IMO, Rolling Upgrade is a significant feature for 0 downtime HDFS. The reminding work looks reasonable to me. Thanks Nicholas and all for hard working on this! CC to yarn-dev, look forward to see YARN Rolling Upgrade can onboard soon (YARN-666). Cheers, Junping - Original
