Just remembered: you'll also need to update python/docs/pyspark.ml.rst for doc gen

jkbradley · 2017-03-25T00:43:41Z

RAT tests are for checking that the Apache license appears at the top of each file

Thanks for the PR! I made a first review pass.

python/pyspark/ml/tests.py

This is a little arbitrary, but to follow other examples, write this as: test_chisquaretest

jkbradley · 2017-03-25T00:51:03Z

python/pyspark/ml/stat.py

Mark as Experimental (Search for other example of this)

Also, we put the triple-quotes on their own line elsewhere in pyspark

jkbradley · 2017-03-25T00:51:30Z

python/pyspark/ml/tests.py

Use DenseVector, not _convert_to_vector. (use public APIs wherever possible)

jkbradley · 2017-03-25T00:52:41Z

python/pyspark/ml/tests.py

It can also be nicer to write this in a per-row format, rather than zipping labels and vectors which are defined separately. See other examples of createDataFrame in this file.

Same for the doc test

jkbradley · 2017-03-25T00:54:04Z

python/pyspark/ml/tests.py

(Noting that this can be updated once the Spark SQL bug is fixed)

jkbradley · 2017-03-25T02:44:49Z

python/pyspark/ml/stat.py

I just saw you changed this from the Scala doc b/c I left "RDD" there. Would you mind correcting the Scala doc too?

jkbradley · 2017-03-25T03:08:45Z

python/pyspark/ml/stat.py

Copy param text from the Scala doc, unless there's a need to customize it for Python

Same for the return value text

dev/sparktestsupport/modules.py

        "pyspark.ml.linalg.__init__",
        "pyspark.ml.recommendation",
        "pyspark.ml.regression",
+        "pyspark.ml.stat",


We just took it out in 314cf51 , but since this is adding back in ml.stat we also need to update setup.py (you might need to update your branch from the latest master to see this).

@holdenk thanks for catching that, should be fixed now.

Wait, do we need to update setup.py? This is creating a module, not a package, right?

Sub-modules aren't automatically packaged so we do need to explicitly add it.

Thanks @jkbradley, I reverted setup.py.

@holdenk If we need to add pyspark.ml.stat to setup.py, then why are we not adding the other analogous modules: pyspark.ml.{classification, clustering, regression,...}?

Oh yah sorry, its anything which is a new sub-directory and when I was reading this PR yesterday I thought this was a new directory, but looking it today that isn't the case, sorry.

OK, no problem, I just wanted to check.

holdenk

Quick read through, thanks for working on this :)

I don't think this test is using the temp path?

Thanks for cleaning up the numpy imports :) +1
