>
> When a cluster contains millions of DNs, *GetDatanodeReport* is pretty
> expensive, and it will cause a large GC pressure on NameNode.
> When multiple NSs share the millions DNs by federation and the router listens
> to the NSs, the problem will be more serious.
> All the NSs will be GC at the same time.
> RBF should cache the datanode report informations and have an option to
> disable the cache.
