-----------------------------------
Summary: Fix @since when a function doesn't have doc
Key: SPARK-10512
URL: https://issues.apache.org/jira/browse/SPARK-10512
Project: Spark
Issue Type: Improvement
Components: PySpark
Affects Versions: 1.6.0
Reporter: Yu Ishikawa
When I tried to add @since to a function which doesn't have doc, @since didn't
go well. It seems that {{___doc___}} is {{None]} under {{since}} decorator.
