----------------------------------
Pinging [~daryn] [~wheat9] [~kihwal] for opinions based on HDFS-11641
activities.
> NameNode getListing should use FileStatus instead of HdfsFileStatus
> -------------------------------------------------------------------
>
> Key: HDFS-12379
> URL: https://issues.apache.org/jira/browse/HDFS-12379
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: namenode
> Reporter: Zhe Zhang
>
> The public {{listStatus}} APIs in {{FileSystem}} and
> {{DistributedFileSystem}} expose {{FileStatus}} instead of
> {{HdfsFileStatus}}. Therefore it is a waste to create the more expensive
> {{HdfsFileStatus}} objects on NameNode.
> It should be a simple change similar to HDFS-11641. Marking incompatible
> because wire protocol is incompatible. Not sure what downstream apps are
> affected by this incompatibility. Maybe those directly using curl, or writing
> their own HDFS client.
