If a problematic app requires too much resources (let's say 1M+ containers, each of them has 3G containers), int32 will be not enough. > Even if we can cap each app's pending request, we cannot handle the case that there're many running apps, each of them has capped but still significant numbers of pending resources. > So we may possibly need to add getMemoryLong/getVirtualCoreLong to o.a.h.y.api.records.Resource. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscribe@hadoop.apache.org For additional commands, e-mail: yarn-issues-help@hadoop.apache.org
