Devaraj K updated YARN-5764: ---------------------------- Fix Version/s: (was: 2.6.0) > NUMA awareness support for launching containers > ----------------------------------------------- > > Key: YARN-5764 > URL: https://issues.apache.org/jira/browse/YARN-5764 > Project: Hadoop YARN > Issue Type: New Feature > Components: nodemanager, yarn > Affects Versions: 2.6.0 > Environment: SW: CentOS 6.7, Hadoop 2.6.0 > Processors: Intel Xeon CPU E5-2699 v4 @2.20GHz > Memory: 256GB 4 NUMA nodes > Reporter: Olasoji > > The purpose of this feature is to improve Hadoop performance by minimizing > costly remote memory accesses on non SMP systems. Yarn containers, on launch, > will be pinned to a specific NUMA node and all subsequent memory allocations > will be served by the same node, reducing remote memory accesses. The current > default behavior is to spread memory across all NUMA nodes. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
