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)

Status REST API uses ApiRootResource main resource class that registers /api/v1 URI path and the subpaths.

Table 1. URI Paths

Path	Description
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

Status REST API uses the following components:

• Jersey RESTful Web Services framework with support for the Java API for RESTful Web Services (JAX-RS API)

• Eclipse Jetty as the lightweight HTTP server and the Java Servlet container
