Eliciting comments for Apache Spark support. With the release of Panda's like DataFrames, it is a little more feasible to directly translate to SparkSQL:

Options in order of complexity:
1. Use the existing Hive connector / translator. Spark still uses the Hive metastore.
2. Thrift JDBC driver. This is what Microstrategy, Tableau, QlikView and others use, most rudimentary API for accessing Spark.
3. Native SparkSQL via building Spark jobs and submitting them to a running Spark driver.
