Removing empty partitions before we write to HDFS
Is there a way to filter out empty partitions before I write to HDFS other
than using reparition and colasce ?

Not that I'm aware of. We ran into the similar "issue" where we didn't want
to keep accumulating all these empty part files in storage on S3 or HDFS.
There didn't seem to be any performance free way to do it with an RDD, so
we just run a non-spark post-batch operation to delete empty files from the
write path.

Currently, I use rdd.isEmpty()
