> INodeFile#diskspaceConsumed() checks the state of the file and use the full block size for the last block if it is under construction.  This is incorrect, because a file can be under construction but the last block is already finalized. It should check the status of the last block instead.
> This issue was fixed in 2.1.0 when the snapshot feature was merged. A subtask, HDFS-4503, consolidated several methods and as a result this bug disappeared.
> A separate fix is needed for 0.23.
