Wangda Tan commented on YARN-5764: ---------------------------------- [~devaraj.k], bq. I can take it up this task to split the common code from YARN-6620 to separate JIRA to handle the NM recovery of assigned resources. Sounds good, you can create a JIRA and let me know, I can help with reviews. > 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 > Reporter: Olasoji > Assignee: Devaraj K > Attachments: NUMA Awareness for YARN Containers.pdf, NUMA Performance > Results.pdf, YARN-5764-v0.patch, YARN-5764-v1.patch, YARN-5764-v2.patch, > YARN-5764-v3.patch > > > 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 (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
