Zhe Zhang created HDFS-12379:
--------------------------------
Summary: 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.
