> The propose is to create customizable auxiliary services infrastructure for all YARN services to provide abilities to extends or change functionality for all YARN demons.
> Currently, YARN has the ability to add auxiliary services only for NodeManager.
> There are some cases when we need to add auxiliary services for some other YARN demons. For example, in YARN-2267 proposed to add Auxiliary Service support in RM for implementation monitor plugins or some alarm services. We faced with one more case, we need to create/setup some storage for YARN demon data (for example for RM state store or AM intermediate data) before demon started. Also, will be good if we can use some auxiliary service in different YARN demons.
> The end users can use YARN Auxiliary Services (YAS) to customize or extend the functionality of all YARN demons. We can provide an ability to create aux service both for one and for all demons. This will make easy creating of aux service for shuffle or just to up some service within another YARN daemon. We will get a unified and more extensible architecture for all aux services which may need to create in the future.
> Please look at the attached design doc for the details. [^Pluggable YARN Auxiliary Services Doc v1.pdf]
