> -------------------------------------------------------

> Key: SPARK-25927
> URL: https://issues.apache.org/jira/browse/SPARK-25927
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.4.0
> Reporter: Maxim Gekk
> Priority: Minor
>
> Currently default number of partitions returned by the outputPartitioning() method of SparkPlan is 0 that doesn't reflect to actual number of partitions for some execution nodes. To return actual number, need to override the outputPartitioning() method in child nodes and implement it properly.
