@Michael Bronson Yes, service checks can still fail even after successful restart of yarn service. This is because the YARN service checks runs some jobs like following which might fail due to some memory issues (even though RM and NM might be running fine) Example: # yarn org.apache.hadoop.yarn.applications.distributedshell.Client -shell_command ls -num_containers 1 -jar /usr/hdp/current/hadoop-yarn-client/hadoop-yarn-applications-distributedshell.jar -timeout 300000 --queue default . So if service check is failijng then we should check the logs to find out why it failed, we might see some errors on the YARN logs indicating memory issue or container creation related issues or something else. ...
