      Description

      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.
