Tejas Patil created SPARK-18038:
-----------------------------------
Summary: Move output partitioning definition from UnaryNodeExec to
its children
Key: SPARK-18038
URL: https://issues.apache.org/jira/browse/SPARK-18038
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 2.0.1
Reporter: Tejas Patil
Priority: Trivial
This was a suggestion by [~rxin] over one of the dev list discussion :
http://apache-spark-developers-list.1001551.n3.nabble.com/Project-not-preserving-child-partitioning-td19417.html

I think this is very risky because preserving output partitioning should not be
a property of UnaryNodeExec (e.g. exchange).
It would be better (safer) to move the output partitioning definition into each
of the operator and remove it from UnaryExecNode.
