Daniel Templeton commented on YARN-5599:

The original intent was to cover for the removal of a log message from the RM 
that output the launch command.  With the log message gone, we wanted to have 
another source for the launch command so that launch failures can be debugged.

> To aid in debugging launch failures, it would be valuable to have an 
> application's launch script and logs posted to ATS.  Because the 
> application's command line may contain private credentials or other secure 
> information, access to the data in ATS should be restricted to the job owner, 
> including the at-rest data.
> Along with making the data available through ATS, the configuration parameter 
> introduced in YARN-5549 and the log line that it guards should be removed.
