Steve Loughran commented on SLIDER-94:
--------------------------------------
HADOOP-9626 covers a {{getExitCode()}} interface for tests that can serve up
errors -this is needed by the service launcher to convert raised exceptions
into the exit codes chosen by the application.
> Get YARN utility features into yarn-common

> Issue Type: Improvement
> Components: core
> Reporter: Steve Loughran

>
> There are some utility classes/services that were generic to YARN, and which
> are better off there now that we've iterated through using them
> # {{ServiceLauncher}} entry point, exit codes and exceptions. This will need
> tests.
> # workflow services: sequence, compound, event
> # cleanup services (web, IPC, closeable). These should be templatized first.
> If we get these into Hadoop 2.5 we can switch to the yarn-packaged successors
> to the internal implementations.
