In ranking_metrics_example.py (https://github.com/apache/spark/blob/master/examples/src/main/python/mllib/ranking_metrics_example.py)
there is this comment:
# Several of the methods available in scala are currently missing from pyspark
Just wanted to know what are the missing methods.
Also, the file actually does regression metrics, unlike the RankingMetricsExample.scala file which actually demo a few ranking metrics. Is the Python example out of date?
