Jun Gong created YARN-3389: ------------------------------ Summary: Two attempts might operate on same data structures concurrently Key: YARN-3389 URL: https://issues.apache.org/jira/browse/YARN-3389 Project: Hadoop YARN Issue Type: Bug Components: resourcemanager Affects Versions: 2.6.0 Reporter: Jun Gong Assignee: Jun Gong
In AttemptFailedTransition, the new attempt will get state('justFinishedContainers' and 'finishedContainersSentToAM') reference from the failed attempt. Then the two attempts might operate on these two variables concurrently, e.g. they might update 'justFinishedContainers' concurrently when they are both handling CONTAINER_FINISHED event. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
