Subject Re: Restful WS for Spark

I worked with both, so I'll give you some insight from my perspective.

spark-jobserver has stable API and overall mature but doesn't work with
yarn-cluster mode and python support is in-development right now.

Livy has stable API (but I'm not sure if I can speak for it since it has
appeared recently but considering that Cloudera is behind of it, I'd say
it's mature), supports all deployment modes and has support for python & R.

spark-jobserver has nicer UI and better features overall for logging and
richer API.

I had hard time adding more features to spark-jobserver than into Livy, so
if it's something you would need to do you should consider that.

In some cases, spark-jobserver runs into issues that are difficult to debug
because of Akka.

Spark-jobserver is better if you use Scala and you need to work with shared
spark contexts as it has built-in API for shared RDDs and objects.

Both don't support High-Availability, but Livy has few open active PRs.

I'd start with spark-jobserver as it's easier.
