> Currently in the new migration tool Mover, we allow users to specify a list of paths
for migration. Then in {{Mover#processNamespace}} we directly call {{getFileInfo}} to retrieve
the status of the given path. If the given path is a file, the returned HdfsFileStatus does
not contain block location information, this can trigger an NPE.
