def listFiles(filters: Seq[Expression]): Seq[PartitionDirectory]

Returns all valid files grouped into partitions when the data is partitioned.
Returns all valid files grouped into partitions when the data is partitioned. If the data is unpartitioned, this will return a single partition with no partition values.
filters
The filters used to prune which partitions are returned. These filters must only refer to partition columns and this method will only return files where these predicates are guaranteed to evaluate to true. Thus, these filters will not need to be evaluated again on the returned data.

def listLeafFiles(paths: Seq[Path]): LinkedHashSet[FileStatus]

List leaf files of given paths.
List leaf files of given paths. This method will submit a Spark job to do parallel listing whenever there is a path having more files than the parallel partition discovery discovery threshold.
This is publicly visible for testing.
