Available interfaces

You can use one of several programmatic interfaces when interacting withDataproc. These are the available interfaces, in the order thatwe recommend using them:

• Google Cloud Client Libraries:Dataproc(alpha and beta release)client libraries are available in multiple languages andare built ongRPC. These clientlibraries provide a layer of abstraction on top ofgRPC and handle the details of operation polling, retries, and more.

  Note: Although the Cloud Client Libraries are the preferred library choice,Google API Client Librariesfor Dataprocare also available. These "legacy" libraries access REST but not gRPCAPIs (seeGoogle API Client Libraries for additional information).

• gRPC: If a client library is not availablefor your programming language of choice, you can generate gRPC clientlibraries for Dataproc in any gRPC-supported language. To do this, you'llneed theprotocol buffers service definition available fromour repository on GitHub.You can then follow the instructions for your preferred language ongrpc.io to generate and use yourclient.

• REST API: If you're unableto use Dataproc's client libraries or the gRPC API, use the REST API.
