Brett Randall resolved HDFS-5478.
---------------------------------

    Resolution: Duplicate

Closed, duplicate, fixed in 2.0.3, solution requires {{FSDataOutputStream}} to be cast to {{HdfsDataOutputStream}} to call an overloaded {{hsync}} method.

> Using a Java client to write to a FSDataOutputStream.  After some data is written and hsync() is called, {{hdfs dfs -get /path/to/file}} gets a file containing the data written so-far, all good.
> {{hdfs dfs -ls /path/to/file}} however reports a zero-byte file, presumably until the stream is closed (it then shows the correct size).  Hue File Browser (running CDH4) also shows zero bytes until the stream is closed.
> See also http://grokbase.com/t/hadoop/hdfs-user/113j63nrce/zero-file-size-after-hsync which discusses the same problem.
> After the buffer is flushed it would be good if the reported file size was updated.
