Allen Wittenauer commented on YARN-7127:
----------------------------------------

bq.  With that assumption, will a separate service subcommand make sense ? 

Let's test that assumption.

Would a user be able to replace the bundled AM with their own and retain all of 
the functionality?

If someone wanted to replicate the native services features, would they be able 
to do it using only Public APIs?

bq.  User end up having a larger set of options and need to read through the 
docs to figure out which ones are applicable to service, or which ones are 
applicable to all apps. 

They'd have to do this anyway whether the commands are spit apart or not.  In 
fact, it's worse if they are split because now there are two sets of commands 
that work different and apply to different applications.  e.g., I can't use the 
proposed 'yarn service' command to stop MapReduce.
