Wangda Tan commented on YARN-796: --------------------------------- Hi guys, I've just created a shadow umbrella JIRA (YARN-2492) for YARN-796 (because YARN-796 is a sub JIRA), and created a bunch of sub tasks under it. I also updated a diagram for YARN-796 (YARN-796-Diagram.pdf), hopefully it can make you have better understanding of the overall structure and flow. *Summary of sub tasks:* * User API changes: YARN-2493 * NodeLabelManager implementation: YARN-2494 (Depends on YARN-2493) * CapacityScheduler side changes: YARN-2496 (Depends on YARN-2494) * Respect labels when do preemption in CS: YARN-2498 (Depends on YARN-2496) * Other changes in RM to support labels: YARN-2500 * Changes in AMRMClient to support labels: YARN-2501 (Depends on YARN-2493) * Changes in Distributed Shell to support labels: YARN-2502 (Depends on YARN-2501) * WebUI/RMAdmin-CLI/REST-API: YARN-2503, YARN-2504, YARN-2505 (Depends on YARN-2494, YARN-2496, YARN-2500) [~yufeldman], do you agree about the basic proposal? I think API expose to users of our proposals are similar but different in implementation. Please feel free to add your comments. Thanks a lot!

Examples of labels > are OS, processor architecture etc. > We should expose these labels and allow applications to specify labels on > resource-requests. > Obviously we need to support admin operations on adding/removing node labels. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
