Summary: Generate different alias for columns with same name
during join
Key: SPARK-11250
URL: https://issues.apache.org/jira/browse/SPARK-11250
Project: Spark
Issue Type: Improvement
Reporter: Davies Liu
It's confusing to see columns with same name after joining, and hard to access
them, we could generate different alias for them in joined DataFrame.
see https://github.com/apache/spark/pull/9012/files#r42696855 as example
