This patch changes PySpark so that the GatewayServer's port is communicated back to the Python process that launches it over a local socket instead of a pipe. The old pipe-based approach was brittle and could fail if `spark-submit` printed unexpected to stdout. To accomplish this, I wrote a custom `PythonGatewayServer.main()` function to use in place of Py4J's `GatewayServer.main()`. Closes #3424. Author: Josh Rosen <joshrosen@databricks.com> Closes #4603 from JoshRosen/SPARK-2313 and squashes the following commits: 6a7740b [Josh Rosen] Remove EchoOutputThread since it's no longer needed 0db501f [Josh Rosen] Use select() so that we don't block if GatewayServer dies. 9bdb4b6 [Josh Rosen] Handle case where getListeningPort returns -1 3fb7ed1 [Josh Rosen] Remove stdout=PIPE 2458934 [Josh Rosen] Use underscore to mark env var. as private d12c95d [Josh Rosen] Use Logging and Utils.tryOrExit() e5f9730 [Josh Rosen] Wrap everything in a giant try-block 2f70689 [Josh Rosen] Use stdin PIPE to share fate with driver 8bf956e [Josh Rosen] Initial cut at passing Py4J gateway port back to driver via socket
