> Error message for discovered conflicting partition columns is not intuitive
> ---------------------------------------------------------------------------

> Key: SPARK-8138
> URL: https://issues.apache.org/jira/browse/SPARK-8138
> Project: Spark
> Issue Type: Improvement
> Components: SQL

> Priority: Minor
> Fix For: 1.5.0

>
> For data stored as a Hive-style partitioned table, data files should only
> live in leaf partition directories.
> For example, the following directory layout is illegal:
> {noformat}
> .
> ├── _SUCCESS
> ├── b=0
> │ ├── c=0
> │ │ └── part-r-00004.gz.parquet
> │ └── part-r-00004.gz.parquet
> └── b=1
> ├── c=1
> │ └── part-r-00008.gz.parquet
> └── part-r-00008.gz.parquet
> {noformat}
> For now, we give an unintuitive error message like this:
> {noformat}
> Conflicting partition column names detected:
> ArrayBuffer(b, c)
> ArrayBuffer(b)
> {noformat}
> This should be improved.
