Description

DistCp uses an internal struct CopyListingFileStatus to record metadata. Because this record extends FileStatus, it also relies on the Writable contract from that type. Because DistCp performs its checks on a subset of the fields (i.e., does not actually rely on FileStatus as a supertype), these types should be independent.
