-------------------------------------------
Summary: Fix for race condition in move app and queue cleanup in FS
Key: YARN-8994
URL: https://issues.apache.org/jira/browse/YARN-8994
Project: Hadoop YARN
Issue Type: Bug
Components: fairscheduler
Affects Versions: 3.2.0
Reporter: Wilfred Spiegelenburg
Assignee: Wilfred Spiegelenburg
Similar to YARN-8990 and also introduced by YARN-8191 there is a race condition
while moving an application. The pre-move check looks for the queue and when it
finds the queue it progresses. The real move then retrieves the queue and does
further check before updating the app and queues.
The move uses the retrieved queue object but the queue could have become empty
while checks are performed. If the cleanup runs at that same time the app will
be moved to a deleted queue and lost.
