Prometheus Data Source for Apache Spark

This library is still work-in-progress. The main remaining TODO before GA are:

• Create unit tests and end-to-end tests (via a mock HTTP server)
• Polish the interface
  • Automatically infer start and end time via query predicates
  • Allow reading endpoint from a session wide config
• Clean up the code (especially the JSON parsing part)
• Error handling

Once polished, I will move this over to Databricks' official repository.

Requirements

This library only works with Spark 2.0 or newer and Java 8.
