Major Description
Zeppelin has pluggagle intrepreter abstraction and multiple implementations for different data processing systems like Flink, Spark, Kylin, Ignite, Geode, etc
Apache Beam (incubating) is a new promising project with unified stream\batch processing and it would be great to have an interpreter for it.
This will require creation of Java interpreter first (i.e using existing REPL) as for now Beam only exposes Java API.
