Description
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
