@harsha2010 I added a few comments, but for this example, my intention was
to have a complex chain of feature encoders (maybe using 6+ since the
SimpleTextClassificationPipeline already includes 3 stages), with the focus on
demonstrating how feature transformers can feed into each other, maybe in a
non-linear graph.
This code example actually seems more useful to me as an example of how to
work with HDFS and Hive. I haven't looked at the SQL examples much; do they
cover similar info? I'm wondering where the best place for these topics is.
(But covering them in examples seems valuable to me.)
