Save the YARN file as Service App

You can save a service YARN file initially without starting the service and later refer to this service YARN file while launching other services.

Run the following command to save the simple-httpd-service YARN file:
yarn app -save simple-httpd-service /path/to/simple-httpd-service.json

Saving or launching the service from a YARN file stores a modified version of the YARN file in HDFS. This service specification can then be referenced by other services, allowing users to assemble more complex services.
