Sean Owen commented on SPARK-19392:
-----------------------------------
It's because SPARK-16625 was back-ported to the 1.6.x release in CDH, I guess
because of a customer problem.
It's at
https://github.com/apache/spark/blob/39e2bad6a866d27c3ca594d15e574a1da3ee84cc/sql/core/src/main/scala/org/apache/spark/sql/jdbc/OracleDialect.scala#L33
I could easily back-port SPARK-16625 to 2.0.x and 1.6.x upstream. I don't think
there was a particular reason it wasn't, so I'll ask if there are any
objections and then do so.
