Konstantin Shvachko commented on HDFS-1091:
-------------------------------------------

# {{@Override}} notation for {{Hdfs.listStatusIterator()}} should be un-commented. It would be also useful to add a comment what it overrides, like
{code}
@Override // AbstractFileSystem
{code}
# In the {{Iterator<FileStatus>}} returned by {{Hdfs.listStatusIterator()}} the {{partialListing}} member seem to be redundant. It is already a member of {{DirectoryListing}}, so you can use {{thisListing.getPartialListing()}} instead.
# It would be good to have an explanatory message when you throw {{NoSuchElementException()}} and {{UnsupportedOperationException()}}.
