--------------------------------------
[~smilegator], I just happened to see this JIRA just while looking through the
history. Per https://github.com/apache/spark/pull/13756#issuecomment-237658676,
would this JIRA be resolvable maybe?
> Disallow Duplicate Columns in `partitionBy`, `bucketBy` and `sortBy`
> --------------------------------------------------------------------
>
> Key: SPARK-16041
> URL: https://issues.apache.org/jira/browse/SPARK-16041
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.0.0
> Reporter: Xiao Li
>
> Duplicate columns are not allowed in `partitionBy`, `bucketBy`, `sortBy` in
> DataFrameWriter. The duplicate columns could cause unpredictable results. For
> example, the resolution failure.
> We should detect the duplicates and issue exceptions with appropriate
> messages.
