Eli Collins commented on HADOOP-9626:
-------------------------------------
Forgot to add, since the int code is part of the interface while we're at it
worth considering making the status code an enum rather than an int and
replacing all the terminate(1,..) calls with terminate(FAIL, ..) etc
> Add an interface for any exception to serve up an Exit code

> Project: Hadoop Common

> Various exception included exit codes, specifically
> {{Shell.ExitCodeException}}, {{ExitUtils.ExitException()}}.
> If all exceptions that wanted to pass up an exit code to the main method
> implemented an interface with the method {{int getExitCode()}}, it'd be
> easier to extract exit codes from these methods in a unified way, so
> generating the desired exit codes on the application itself
