[~billie.rinaldi] Thank you for the review.
# I will reduce config object.
# I will reuse RMHAUtils.getRMHAWebappAddress.
# EnableFastLaunch seems to be a problem because Rest API server doesn't have
this functionality. I am more inclined to fix this issue by start up of
Resource Manager to check if the required libraries are uploaded to hdfs, and
remove the enableFastLaunch option. Thoughts?
# I will fix the conflict introduced via YARN-6669.
# I agree that NATIVE_TYPE is confusing, and we need this special type for unit
tests. Therefore, I am inclined to rename NATIVE_TYPE to "unit-test" type for
correctness.

> For YARN docker application to launch through CLI, it works differently from
> launching through REST API. All application launched through REST API is
> currently stored in yarn user HDFS home directory. Application managed
> through CLI are stored into individual user's HDFS home directory. For
> consistency, we want to have yarn app cli to interact with API service to
> manage applications. For performance reason, it is easier to implement list
> all applications from one user's home directory instead of crawling all
> user's home directories. For security reason, it is safer to access only one
> user home directory instead of all users. Given the reasons above, the
> proposal is to change how {{yarn app -launch}}, {{yarn app -list}} and {{yarn
> app -destroy}} work. Instead of calling HDFS API and RM API to launch
> containers, CLI will be converted to call API service REST API resides in RM.
> RM perform the persist and operations to launch the actual application.
