Subject [jira] [Created] (YARN-8060) Create default readiness check for service components
Date Wed, 21 Mar 2018 21:21:00 GMT
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.
