> If quotas are enabled a combination of operations *deleteSnapshot* and
> *delete* of a file can leave orphaned blocks in the blocksMap on NameNode
> restart. They are counted as missing on the NameNode, and can prevent
> NameNode from coming out of safeMode and could cause memory leak during
> startup.
