Hi All,
Based on the discussion at [1], I'd like to start a vote to merge feature branch YARN-5881 to trunk. Vote will run for 7 days, ending Wednesday Dec 6 at 6:00PM PDT. This branch adds support to configure queue capacity as absolute resource in capacity scheduler. This will help admins who want fine control of resources of queues. Feature development is done at YARN-5881 [2], jenkins build is here (YARN-7510 [3]). All required tasks for this feature are committed. This feature changes RM’s Capacity Scheduler only, and we did extensive tests for the feature in the last couple of months including performance tests. Key points: - The feature is turned off by default, and have to configure absolute resource to enable same. - Detailed documentation about how to use this feature is done as part of [4]. - No major performance degradation is observed with this branch work. SLS and UT performance tests are done. There were 11 subtasks completed for this feature. Huge thanks to everyone who helped with reviews, commits, guidance, and technical discussion/design, including Wangda Tan, Vinod Vavilapalli, Rohith Sharma K S, Eric Payne .
