> This started out intended only to support [Spark Connect|https://spark.apache.org/spark-connect/], which is a gRPC-native protocol for Apache Spark that allows end users to interact with Spark clusters and submit jobs through a principled API, from languages that aren't necessarily Python, Scala or SQL. Spark Connect itself explicitly disclaims any support for authentication or authorization; rather Spark suggests installing one's own gRPC gateway between client and server if such functionality is needed. Knox could be that gateway!
> The original intent of this project was only to support Spark Connect rather than arbitrary gRPC workloads, but the Spark Connect-specific parts turned out to be very small, and making it fully generic required very little additional code. Knox doesn't _exactly_ support proxying arbitrary REST traffic right now, but it makes it pretty easy.
