Description

The sql programming guide of spark is out-of-date in many places, including:

should using `SparkSession` instead of `SQLContext`
should using `SparkSession.builder.enableHiveSupport` instead of `HiveContext`
should using `dataFrame.write.saveAsTable` instead of `dataFrame.saveAsTable`
should using `sparkSession.catalog.cacheTable/uncacheTable` instead of `SQLContext.cacheTable/uncacheTable`

and so on...
