There was a problem hiding this comment.
It'd be great to add a comment here that this mimics the hive semantics

…alues. ## What changes were proposed in this pull request? We added native versions of `collect_set` and `collect_list` in Spark 2.0. These currently also (try to) collect null values, this is different from the original Hive implementation. This PR fixes this by adding a null check to the `Collect.update` method. ## How was this patch tested? Added a regression test to `DataFrameAggregateSuite`. Author: Herman van Hovell <hvanhovell@databricks.com> Closes#15208 from hvanhovell/SPARK-17641. (cherry picked from commit 7d09232) Signed-off-by: Reynold Xin <rxin@databricks.com>
