Tsz Wo (Nicholas), SZE updated HDFS-585:
----------------------------------------
Attachment: h585_20090909.patch
h585_20090909.patch: use getBytesOnDisk() instead of file length.
> 2. Should we have unit tests testing reading from an unclosed file?
The read function is not yet completed. So it is hard to write unit tests for
this. If you insist, I don't mind to spend time on adding unit tests.
> Datanode should serve up to visible length of a replica for read requests
