-------------------------------------
Sigh. All the tests that failed under Hudson pass on my machine. Two were
obvious time outs, the other probably was as well.

> As discussed in HADOOP-4954, it would be useful to be able to query the

> This would allow ops to compare what the namenode sees with what they expect
> it to see.
