[SPARK-1466] Raise exception if pyspark Gateway process doesn't start.
If the gateway process fails to start correctly (e.g., because JAVA_HOME
isn't set correctly, there's no Spark jar, etc.), right now pyspark fails
because of a very difficult-to-understand error, where we try to parse stdout
to get the port where Spark started and there's nothing there. This commit
properly catches the error and throws an exception that includes the stderr
output for much easier debugging.
Thanks to @shivaram and @stogers for helping to fix this issue!
