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)
