---------------------------------------
Summary: Keep broadcast hint after column pruning
Key: SPARK-13383
URL: https://issues.apache.org/jira/browse/SPARK-13383
Project: Spark
Issue Type: Bug
Components: SQL
Reporter: Liang-Chi Hsieh
When we do column pruning in Optimizer, we put additional Project on top of a
logical plan. However, when we already wrap a BroadcastHint on a logical plan,
the added Project will hide BroadcastHint after later execution.
