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 (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscribe@hadoop.apache.org For additional commands, e-mail: yarn-issues-help@hadoop.apache.org
