If a _SUCCESS appears in the inner partitioning dir, partition discovery will treat that _SUCCESS file as a data file. Then, partition discovery will fail because it finds that the dir structure is not valid. We should ignore those `_SUCCESS` files. In future, it is better to ignore all files/dirs starting with `_` or `.`. This PR does not make this change. I am thinking about making this change simple, so we can consider of getting it in branch 1.6. To ignore all files/dirs starting with `_` or `, the main change is to let ParquetRelation have another way to get metadata files. Right now, it relies on FileStatusCache's cachedLeafStatuses, which returns file statuses of both metadata files (e.g. metadata files used by parquet) and data files, which requires more changes. https://issues.apache.org/jira/browse/SPARK-13207 Author: Yin Huai <yhuai@databricks.com> Closes #11088 from yhuai/SPARK-13207.
