Description

Yarn (native) services has been added to Hadoop Yarn in the 3.1.0 release. Since then it has evolved and has had lots of bugfixes/stabilizations committed to Hadoop. Though the feature is still not considered stable officially, lots of production clusters using Hadoop 3.1.0+ benefit from it.

YARN services has great value to the end-users and has the following features:

• performs configuration resolutions and mounts,
• lifecycle management such as stop/start/delete the service,
• flexing service components up/down,
• rolling upgrades services on YARN
• monitoring services’ healthiness and readiness and more. [1]

It would be nice if Oozie was able to handle Yarn services along with traditional applications.
