[jira] [Commented] (SPARK-26016) Encoding not working when using a
map / mapPartitions call
[ https://issues.apache.org/jira/browse/SPARK-26016?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16766690#comment-16766690 ]

--------------------------------------
Okay, can you make the input / output in JIRA's description? I don't think many people try to actually download and verify it. Scala and Java APIs are virtually same. Is there easier way to reproduce the issue with Scala shall?

> Affects Versions: 2.4.0

> 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.
