>                 Key: YARN-6202

>             Project: Hadoop YARN
>          Issue Type: Bug
>          Components: nodemanager, resourcemanager
>    Affects Versions: 2.9.0, 3.0.0-alpha2

> Dispatcher.DISPATCHER_EXIT_ON_ERROR_KEY (yarn.dispatcher.exit-on-error) always be true
no matter what value in configuration files. This misleads users. Two solutions: 
> # Remove the configuration item but also allow it to be false to enable some unit tests,
the assumption is there is no need for false value in product env.
> # Make it default true instead of false, so that we don't need to hard code in RM and
NM, it is still configurable. 
> Other than that, the code around it needs to refactor. {{public static final}} for a
variable of interface isn't necessary, and YARN related configure item should be in class
YarnConfiguration.
