Panagiotis Garefalakis reassigned YARN-7839: -------------------------------------------- Assignee: Panagiotis Garefalakis > Check node capacity before placing in the Algorithm > --------------------------------------------------- > > Key: YARN-7839 > URL: https://issues.apache.org/jira/browse/YARN-7839 > Project: Hadoop YARN > Issue Type: Sub-task > Reporter: Arun Suresh > Assignee: Panagiotis Garefalakis > Priority: Major > > Currently, the Algorithm assigns a node to a request purely based on if the > constraints are met. It is later in the scheduling phase that the Queue > capacity and Node capacity are checked. If the request cannot be placed > because of unavailable Queue/Node capacity, the request is retried by the > Algorithm. > For clusters that are running at high utilization, we can reduce the retries > if we perform the Node capacity check in the Algorithm as well. The Queue > capacity check and the other user limit checks can still be handled by the > scheduler (since queues and other limits are tied to the scheduler, and not > scheduler agnostic) -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
