Sandy Ryza commented on YARN-2413: ---------------------------------- I believe this is the expected behavior (i.e. Capacity Scheduler by default doesn't use vcores in scheduling). > capacity scheduler will overallocate vcores > ------------------------------------------- > > Key: YARN-2413 > URL: https://issues.apache.org/jira/browse/YARN-2413 > Project: Hadoop YARN > Issue Type: Bug > Components: scheduler > Affects Versions: 3.0.0, 2.2.0 > Reporter: Allen Wittenauer > Priority: Critical > > It doesn't appear that the capacity scheduler is properly allocating vcores > when making scheduling decisions, which may result in overallocation of CPU > resources. -- This message was sent by Atlassian JIRA (v6.2#6252)
