An REST Service for Apache Spark
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 is a service that enables easy interaction with a Spark cluster over a REST interface. It enables easy submission of Spark jobs or snippets of Spark code, synchronous or asynchronous result retrieval, as well as Spark Context management, all via a simple REST interface or a RPC client library. Apache Livy also simplifies the interaction between Spark from application servers, thus enabling the use of Spark for interactive web/mobile applications. Additional features include:
