      Description

      This new dataset property means that CDAP does not own the underlying data. That is, for a file set, it will not attempt to create the base directory, it will not allow writing files, and it will not delete the files when the dataset is deleted.

      For a partitioned file set this means that upon delete, partitions are still subject to delete, but the underlying files will not be touched.
