Interface LauncherExitCodes

All Known Implementing Classes:
ServiceLaunchException
@Public @Evolving public interface LauncherExitCodes
Common Exit codes.

Codes with a YARN prefix are YARN-related.

Many of the exit codes are designed to resemble HTTP error codes, squashed into a single byte. e.g 44 , "not found" is the equivalent of 404. The various 2XX HTTP error codes aren't followed; the Unix standard of "0" for success is used. 

    0-10: general command issues
   30-39: equivalent to the 3XX responses, where those responses are
          considered errors by the application.
   40-49: client-side/CLI/config problems
   50-59: service-side problems.
   60+  : application specific error codes
