> The {{BlockManager#removeFromExcessReplicateMap()}} method accepts a {{Block}} which
is to remove from {{excessReplicateMap}}. However the {{excessReplicateMap}} maps a StorageID
to the set of {{BlockInfo}} that are "extra" for the DataNode of the StorageID. Deleting a
sub-class object from a collection provided a base-class object happens to work here.
> Alternatively, we can make the {{removeFromExcessReplicateMap}} accept a {{BlockInfo}}
object. As the current call stack is passing {{BlockInfo}} object mostly, the code change
should be safe.
