Carlo Curino commented on YARN-4360: ------------------------------------ This patch depends on YARN-4358. > Improve GreedyReservationAgent to support "early" allocations, and > performance improvements > -------------------------------------------------------------------------------------------- > > Key: YARN-4360 > URL: https://issues.apache.org/jira/browse/YARN-4360 > Project: Hadoop YARN > Issue Type: Sub-task > Components: capacityscheduler, fairscheduler, resourcemanager > Reporter: Carlo Curino > Assignee: Carlo Curino > Attachments: YARN-4360.patch > > > The GreedyReservationAgent allocates "as late as possible". Per various > conversations, it seems useful to have a mirror behavior that allocates as > early as possible. Also in the process we leverage improvements from > YARN-4358, and implement an RLE-aware StageAllocatorGreedy(RLE), which > significantly speeds up allocation. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
