> The information presented by hadoop dfs -report is incorrect.
> In the following example, the total raw bytes are correct, the used raw bytes are incorrect
and should actually be on the order of 138TB.
> The total effective bytes is correct, and the actual replication factor is really a healthy
3.
> yarnon@g1010:build:942>hadoop dfs  2> /dev/null -report | head
> Total raw bytes: 240761579888640 (224226.69 Gb)
> Used raw bytes: 35934229005360 (33466.35 Gb)

> In the following example again the total raw bytes and total effective bytes are correct,
but the used raw bytes, % used and effective replication are a tad off the mark.
