Corey created SPARK-19734:
-----------------------------
Summary: OneHotEncoder __init__ uses dropLast but doc strings all
say includeFirst
Key: SPARK-19734
URL: https://issues.apache.org/jira/browse/SPARK-19734
Project: Spark
Issue Type: Documentation
Components: PySpark
Affects Versions: 2.1.0, 2.0.2, 1.6.3, 1.5.2
Reporter: Corey
Priority: Minor
The {{OneHotEncoder.__init__}} doc string in PySpark has an input keyword
listed as {{includeFirst}}, whereas the code actually uses {{dropLast}}.
This especially confusing because the {{__init__}} function accepts only
keywords, and following the documentation on the web
(https://spark.apache.org/docs/2.0.1/api/python/pyspark.ml.html#pyspark.ml.feature.OneHotEncoder)
or of {{help}} in Python will result in the error:
{quote}
TypeError: __init__() got an unexpected keyword argument 'includeFirst'
{quote}
The error is immediately viewable in the source code:
{code}
@keyword_only
def __init__(self, dropLast=True, inputCol=None, outputCol=None):
"""
__init__(self, includeFirst=True, inputCol=None, outputCol=None)
"""
{code}
