             Summary: Stuck in express_upgrading if there is any component which has no instance
                 Key: YARN-10203
                 URL: https://issues.apache.org/jira/browse/YARN-10203
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: kyungwan nam
            Assignee: kyungwan nam


I was trying to "express upgrade" which introduced in YARN-8298.
https://hadoop.apache.org/docs/r3.2.0/hadoop-yarn/hadoop-yarn-site/yarn-service/ServiceUpgrade.html

but, service state stuck in EXPRESS_UPGRADING.
It happens only If there is any component that has no instance. ("number_of_containers" : 0)

the component which has no instance should be excepted from upgrade target
