---------------------------------------
Summary: Upgrading to 3.1 kills running containers with error
"Opportunistic container queue is full"
Key: YARN-8346
URL: https://issues.apache.org/jira/browse/YARN-8346
Project: Hadoop YARN
Issue Type: Bug
Reporter: Rohith Sharma K S
It is observed while rolling upgrade from 2.8.4 to 3.1 release, all the running
containers are killed and second attempt is launched for that application. The
diagnostics message is "Opportunistic container queue is full" which is the
reason for container killed.
In NM log, I see below logs for after container is recovered.
