Weiwei Yang created YARN-8127: --------------------------------- Summary: Resource leak when async scheduling is enabled Key: YARN-8127 URL: https://issues.apache.org/jira/browse/YARN-8127 Project: Hadoop YARN Issue Type: Bug Reporter: Weiwei Yang
Brief steps to reproduce # Enable async scheduling, 5 threads # Submit a lot of jobs trying to exhaust cluster resource # After a while, observed NM allocatedĀ resourceĀ is more than resource requested by allocated containers Looks like the commit phase is not sync handling reserved containers, causing some proposal incorrectly accepted, subsequently resource was deducted multiple times for a container. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-dev-h...@hadoop.apache.org
