------------------------------
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.
