Status REST API — Monitoring Spark Applications Using REST API

Status REST API is a collection of REST endpoints under /api/v1 URI path in the root containers for application UI information:

SparkUI – Application UI for an active Spark application (i.e. a Spark application that is still running)
HistoryServer – Application UI for active and completed Spark applications (i.e. Spark applications that are still running or have already finished)

`applications`	Delegates to the ApplicationListResource resource class
`applications/{appId}`	Delegates to the OneApplicationResource resource class
`version`	Creates a `VersionInfo` with the current version of Spark
