> Components: namenode
> Affects Versions: 3.0.0, 2.4.0
> Reporter: Suresh Srinivas

>
> When a directory that has large number of directories and files are deleted,
> the namespace deletes the corresponding inodes immediately. However it is
> hard to to know when the invalidated blocks are actually deleted on the
> datanodes, which could take a while.
> I propose adding on namenode webUI, along with under replicated blocks, the
> number of blocks that are pending deletion.
