Great job. Exciting to see this new feature in Zeppelin.
My two cents:
> through thrift in yarn-cluster mode
Cloudera's Spark don't have thrift service and Cloudera doesn't recommend
to use that (they quote security is one of the concerns there).
So I also think spark-submit would be a better option (either it's on a
remote or local machine, yarn-cluster or yarn-client).
> But that remote machine may not have the spark configuration (like
spark-defualts.conf, hive-site.xml).
Not sure how big this of a concern. We normally have all hadoop servers and
gateway servers identical all hadoop-related configuration files (it's managed
by Cloudera Manager for us).
