[jira] [Created] (YARN-8060) Create default readiness check for service components

Billie Rinaldi created YARN-8060:
------------------------------------

             Summary: Create default readiness check for service components
                 Key: YARN-8060
                 URL: https://issues.apache.org/jira/browse/YARN-8060
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: yarn-native-services
            Reporter: Billie Rinaldi
            Assignee: Billie Rinaldi


It is currently possible for a component instance to have READY status before the AM retrieves an IP for the container. We should make sure the IP has been retrieved before marking the instance as READY.

This default probe could also have an option to check for a DNS entry for the instance's hostname if a DNS address is provided.
