Jakob Homan commented on HDFS-538: ---------------------------------- @Todd - why the change in release note? The previous version better covered the change and provided a clue to clients at the change they need to make. > DistributedFileSystem::listStatus incorrectly returns null for empty result > sets > -------------------------------------------------------------------------------- > > Key: HDFS-538 > URL: https://issues.apache.org/jira/browse/HDFS-538 > Project: Hadoop HDFS > Issue Type: Bug > Reporter: Jakob Homan > Assignee: Jakob Homan > Fix For: 0.21.0 > > Attachments: HDFS-538.patch > > > Currently the listStatus method returns null if no files match the request. > This differs from the Checksum/LocalFileSystem implementation, which returns > an empty array, and the nontvery-explict prescription of the FileSystem > interface: "{...@return the statuses of the files/directories in the given > patch}}" It's better to return an empty collection than have to add extra > null checks. The method should return an empty array. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
