+1 (binding) Thanks Andrew Wang for driving this effort and also thanks to all others who helped in this release. Kudos!!!
I tested this RC by building it from source. I met with couple of issues (not blocker) HADOOP-15116 and YARN-7650. This could be tracked separately. - Ran many MR apps and verified both new YARN UI and old RM UI. - Tested below feature sanity and got results as per the behavior - Application priority (verified CLI/REST/UI etc) - Application timeout - Intra Queue preemption with priority based - Inter Queue preemption - Tested basic NodeLabel scenarios. - Added couple of labels to few of nodes and behavior is coming correct. - Verified old UI and new YARN UI for labels. - Submitted apps to labelled cluster and it works fine. - Also performed few cli commands related to nodelabel. - Test basic HA cases and seems correct. However I got one issue. Raised HADOOP-15116 as its not a blocker. - Also tested new YARN UI . All pages are getting loaded correctly. (User must enable CORS to access NodeManager pages) - *Performance test*: I ran a tight loop perf test on CS TestCapacitySchedulerPerf#testUserLimitThroughputForTwoResources. Results are a bit off w.r.t 2.8 (~5% less). I will open a ticket and investigate by doing more tests to see if its to be addressed or not. - Sunil G On Sat, Dec 9, 2017 at 2:01 AM Andrew Wang <andrew.w...@cloudera.com> wrote: > Hi all, > > Let me start, as always, by thanking the efforts of all the contributors > who contributed to this release, especially those who jumped on the issues > found in RC0. > > I've prepared RC1 for Apache Hadoop 3.0.0.
