Would like to see interests of Redis interpreter

[Jungtaek Lim]

Hi devs,

I'd like to see the community interest for the Redis interpreter.

Redis is not a Hadoop ecosystem but always on top ranks on NoSQL.
Unfortunately it officially provides only CLI, not Web or REST API, which
is another advantage of (Zeppelin and Redis) community for integrating to
Web UI. It supports various data types, and while it's not a Hadoop
ecosystem, but it's occasionally used for sink and state storage of
streaming framework.

I'm planning to work on when we would like to have this one.

Thanks in advance,
