> PartitioningAwareFileCatalog.allFiles doesn't handle URI specified path at
> parent
> ---------------------------------------------------------------------------------
>
> Key: SPARK-17613
> URL: https://issues.apache.org/jira/browse/SPARK-17613
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.0.0
> Reporter: Burak Yavuz
>
> Consider you have a bucket as
> {code}
> s3a://some-bucket
> {code}
> and under it you have files:
> {code}
> s3a://some-bucket/file1.parquet
> s3a://some-bucket/file2.parquet
> {code}
> Getting the parent path of {code}s3a://some-bucket/file1.parquet{code}
> yields
> {code}s3a://some-bucket/{code}
> and the ListingFileCatalog uses this as the key in the hash map.
> When catalog.allFiles is called, we use {code}s3a://some-bucket{code} (no
> slash at the end) to get the list of files, and we're left with an empty list!
