> If a data node is added to the exclude list and the name node is restarted, 
> the decomissioning happens right away on the data node registration. At this 
> point the initial block report has not been sent, so the name node thinks the 
> node has zero blocks and the decomissioning completes very quick, without 
> replicating the blocks on that node.
