In Kubernetes, a way to install and manage an application. Kubernetes operators handle not just application installation, but also the entire application lifecycle, including complex upgrades. An operator consists of a combination of two real Kubernetes objects: a controller and a custom resource. The MapR Kubernetes Ecosystem uses different types of operators to facilitate compute applications. For example, the CSpace Operator creates CSpace namespaces for running compute applications. The Spark Operator starts Spark jobs inside a previously created CSpace. And the Drill Operator starts a set of Drillbits in a previously created CSpace.
