Chris Douglas updated HDFS-12681:
---------------------------------
Attachment: HDFS-12681.15.patch
Fixed a checkstyle issue.
Filed MAPREDUCE-7016 to track the 2-RPC case for {{FileInputFormat}}, which is
where most of the failures from v10 originated. Fixing it is not
straightforward, as globbing in {{FileSystem}} needs to work around a lot of
legacy constraints. Many are documented, but some may require working with HDFS
to retain the semantics of hidden directories, snapshots, etc.
> Make HdfsLocatedFileStatus a subtype of LocatedFileStatus

> {{HdfsLocatedFileStatus}} is a subtype of {{HdfsFileStatus}}, but not of
> {{LocatedFileStatus}}. Conversion requires copying common fields and shedding
> unknown data. It would be cleaner and sufficient for {{HdfsFileStatus}} to
> extend {{LocatedFileStatus}}.
