[jira] Created: (HDFS-879) FileStatus should have the visible length of the file

FileStatus should have the visible length of the file
-----------------------------------------------------

                 Key: HDFS-879
                 URL: https://issues.apache.org/jira/browse/HDFS-879
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Zheng Shao
            Assignee: Zheng Shao


Currently, {{FileStatus}} returned by {{DistributedFileSystem.listStatus()}} (which goes through {{DFSClient.listPath()}} then {{NameNode.getListing()}}) does not have the latest file length, if the file is still open for write.

We should make changes in {{DFSClient.listPath()}} to override the length of the file, if the file is under construction.

This depends on adding a {{isUnderConstruction}} field in {{FileStatus}}.
