------------------------------------------
Summary: python_full_outer_join should use generator expression
instead of list comp
Key: SPARK-14202
URL: https://issues.apache.org/jira/browse/SPARK-14202
Project: Spark
Issue Type: Improvement
Components: PySpark
Affects Versions: 1.6.0, 1.5.0, 1.4.0, 1.3.0, 2.0.0
Reporter: Maciej Szymkiewicz
At this moment {{python_full_outer_join}} is the only join operation on Python
RDDs which uses list comprehension instead of generator expression in its
{{dispatch}} function.
It doesn't look like there is any particular reason that could justify this
choice and it can lead to serious performance issues.
