But NM have not > released them at that time. > The problem was found when we supported GPU as a resource(YARN-4122). Test > environment: a NM had 6 GPUs, app A used all 6 GPUs, app B was requesting 3 > GPUs. Killed app A, then RM released A's 6 GPUs, and allocated 3 GPUs to B. > But when B tried to start container on NM, NM found it didn't have 3 GPUs to > allocate because it had not released A's GPUs. > I think the problem also exists for CPU/Memory. It might cause OOM when > memory is overused. -- 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
