Hyukjin Kwon created SPARK-20552:
------------------------------------
Summary: Add isNotDistinctFrom/isDistinctFrom for column APIs in
Scala/Java and Python
Key: SPARK-20552
URL: https://issues.apache.org/jira/browse/SPARK-20552
Project: Spark
Issue Type: Improvement
Components: PySpark, SQL
Affects Versions: 2.2.0
Reporter: Hyukjin Kwon
Priority: Minor
After SPARK-20463, we are able to use {{IS [NOT] DISTINCT FROM}} in Spark SQL.
It looks we should add {{isNotDistinctFrom}} (as an alias for {{eqNullSafe}})
and {{isDistinctFrom}} (for a negated {{eqNullSafe}}) in both Scala/Java and
Python in Column APIs.
