The S3 work really enabled any Hadoop FileSystem to work with Impala, but a small tweak is needed for LocalFileSystem due to how the Hadoop Path code deals with URIs that don't have an authority component. While we aren't claiming support for arbitrary FileSystem's at this tiem, it is useful to test this. Since the S3 testing is done as a nightly test rather than pre-checkin, we can use the LocalFileSystem to regression test that: 1) Impala can access table data living on a secondary filesystem, i.e. not the filesystem specified by fs.defaultFS. 2) Impala does not make assumptions that the filesystem has type DistributedFileSystem.
