Steve Loughran created HADOOP-9626:
--------------------------------------
Summary: Add an interface for any exception to serve up an Exit
code
Key: HADOOP-9626
URL: https://issues.apache.org/jira/browse/HADOOP-9626
Project: Hadoop Common
Issue Type: Improvement
Components: util
Affects Versions: 2.1.0-beta
Reporter: Steve Loughran
Priority: Minor
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
