             Summary: Fix number of partitions returned by outputPartitioning
                 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


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.
