Context management, all via a simple REST interface or an RPC client library. All the nodes supported by Hive and Impala are supported by spark engine. Livy solves a fundamental architectural problem that plagued previous attempts to build a Rest based Spark Server: instead of running the Spark Contexts in the Server itself, Livy manages Contexts running on the cluster managed by a Resource Manager like YARN. This is both simpler and faster, as results don’t need to be serialized through Livy. Currently local files cannot be used (i.e. Multiple Spark Contexts can be managed simultaneously, and the Spark Contexts run on the cluster (YARN/Mesos) instead of the Livy Server, for good fault tolerance and concurrency Jobs can be submitted as precompiled jars, snippets of code or via java/scala client API Ensure security via secure authenticated communication ‎11-11-2016 ‎11-11-2016 did you find a solution to include libraries from internal maven repository? they won't be localized on the cluster when the job runs.)
