> For RS-6-3, when there is one ec block group and
> 1) 0~3 out of 9 internal blocks are missing, NN Web UI doesn't show any warns.
> 2) 4~8 out of 9 internal blocks are missing, NN Web UI shows "There are 1 
> missing blocks." but doesn't show the block names. (please see case_2.png)
> 3) 9 out of 9 internal blocks are missing, NN Web UI shows "There are 1 
> missing blocks." and also shows the block name. (please see case_3.png)
> We should fix the case 2). I think NN Web UI should show the block names 
> since the ec block group is unrecoverable.
> The values come from JMX. "There are X missing blocks." is 
> {{NumberOfMissingBlocks}} and the block names are {{CorruptFiles}}.
