> Project: Hadoop YARN

> Reporter: Suma Shivaprasad

>
> YARN-8080 implements restart capabilities for service component instances.
> YARN service components should add an option to disallow flexing to support
> workloads which are essentially batch/iterative jobs which terminate with
> restart_policy=NEVER/ON_FAILURE. This could be disabled by default for
> components where restart_policy=NEVER/ON_FAILURE and enabled by default when
> restart_policy=ALWAYS(which is the default restart_policy) unless explicitly
> set at the service spec.
> The option could be exposed as part of the component spec as "allow_flexing".
