> In the current deletion logic in NameNode, there are mainly two steps:
> * Collect INodes and all blocks to be deleted, then delete INodes.
> * Remove blocks chunk by chunk in a loop.
> Actually the first step should be a more expensive operation and will takes
> more time. However, now we always see NN hangs during the remove block
> operation.
> Looking into this, we introduced a new structure {{FoldedTreeSet}} to have a
> better performance in dealing FBR/IBRs. But compared with early
> implementation in remove-block logic, {{FoldedTreeSet}} seems more slower
> since It will take additional time to balance tree node. When there are large
> block to be removed/deleted, it looks bad.
> For the get type operations in {{DatanodeStorageInfo}}, we only provide the
> {{getBlockIterator}} to return blocks iterator and no other get operation
> with specified block. Still we need to use {{FoldedTreeSet}} in
> {{DatanodeStorageInfo}}? As we know {{FoldedTreeSet}} is benefit for Get not
> Update. Maybe we can revert this to the early implementation.
