Liang-Chi Hsieh 056883e070 [SPARK-13266] [SQL] None read/writer options were not transalated to "null" ... ## What changes were proposed in this pull request? In Python, the `option` and `options` method of `DataFrameReader` and `DataFrameWriter` were sending the string "None" instead of `null` when passed `None`, therefore making it impossible to send an actual `null`. This fixes that problem. This is based on #11305 from mathieulongtin. ## How was this patch tested? Added test to readwriter.py. Author: Liang-Chi Hsieh <simonh@tw.ibm.com> Author: mathieu longtin <mathieu.longtin@nuance.com> Closes #12494 from viirya/py-df-none-option.		2016-04-22 09:19:36 -07:00
