To validate an app name, the following GET call should be made.
{code}

{
  status: 409,
  message: "Conflict"

If the name is acceptable, 200-OK is returned.

> If YARN is restarted, the list of app names is lost. However, HDFS still has the file names. We need an API to validate if a name is acceptable. Not doing so results in errors when creating an app.
