+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.
