Also a few comments on the doc page
(http://www.cs.berkeley.edu/%7Emarmbrus/sparkdocs/_site/sql-programming-guide.html):
* Put Spark SQL closer to the top of the programming guide and API doc
menus, say under Spark Streaming. I think it will be read more often than some
of the other ones.
* On the API docs, list Spark SQL Core first, then Hive Support, and then
Catalyst Optimizer
* Each package should have a package.scala with a package-level doc for it
(see e.g.
http://www.cs.berkeley.edu/%7Emarmbrus/sparkdocs/_site/api/streaming/index.html#org.apache.spark.streaming.package)
* The doc should explain the types of various things returned (e.g. what is
an ExecutedQuery, what does loadFile return)
* Name the Hive Metastore Support section to just Hive Support, since it
supports the QL as well.
* It would be cool to include an example of running MLlib or something
similar on top of SQL data.
