-------------------------------
Summary: When possible, correctly set outputPartitioning for leaf
SparkPlans
Key: SPARK-5354
URL: https://issues.apache.org/jira/browse/SPARK-5354
Project: Spark
Issue Type: Improvement
Components: SQL
Reporter: Yin Huai
Right now, Spark SQL is not aware of the partitioning scheme of a leaf
SparkPlan (e.g. an input table). So, even users want to re-partitioning the
data in advance, Exchange operators will still be used.
