             Summary: Create a API class for yarn-native-service user-facing constants
                 Key: YARN-6393
                 URL: https://issues.apache.org/jira/browse/YARN-6393
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Jian He


User can use some constants  in the json input spec file for later substitution.
e.g. if user specifies $HOSTNAME in the env section of the input file, it'll be substituted by AM with the actual host name. We'll need to create an API class and clearly documents it.
