[jira] [Created] (SPARK-26016) Encoding not working when using a map / mapPartitions call

Chris Caspanello created SPARK-26016:
----------------------------------------

             Summary: Encoding not working when using a map / mapPartitions call
                 Key: SPARK-26016
                 URL: https://issues.apache.org/jira/browse/SPARK-26016
             Project: Spark
          Issue Type: Bug
          Components: Java API
    Affects Versions: 2.4.0
            Reporter: Chris Caspanello
         Attachments: spark-sandbox.zip

Attached you will find a project with unit tests showing the issue at hand.

If I read in a ISO-8859-1 encoded file and simply write out what was read; the contents in the part file matches what was read.  Which is great.

However, the second I use a map / mapPartitions function it looks like the encoding is not correct.  In addition a simple collectAsList and writing that list of strings to a file does not work either.  I don't think I'm doing anything wrong.  Can someone please investigate?  I think this is a bug.
