A REST Service for Apache SparkGet Livy 0.5.0-incubating
Livy enables programmatic, fault-tolerant, multi-tenant submission of Spark jobs from web/mobile apps (no Spark client needed). So, multiple users can interact with your Spark cluster concurrently and reliably.
Livy speaks either Scala or Python, so clients can communicate with your Spark cluster via either language remotely. Also, batch job submissions can be done in Scala, Java, or Python.
Don’t worry, no changes to existing programs are needed to use Livy. Just build Livy with Maven, deploy the configuration file to your Spark cluster, and you’re off! Check out Get Started to get going.

Apache Livy also simplifies the interaction between Spark and application servers, thus enabling the use of Spark for interactive web/mobile applications. Additional features include:
