Haha, 50 executors? I hope the cluster can handle all that horsepower! But seriously, this looks like a solid solution. Just need to make sure the HADOOP_CONF_DIR is set correctly.

Ah, I see what they're going for. This seems like a straightforward setup for a Spark application on YARN. The only thing I'd double-check is the version of Spark being used, just to make sure the options are still valid.

Looks good! The solution should work just fine. Though, I wonder if the 20GB per executor will be enough for our data processing needs.
