> A command to delete block pool directories from the datanode is required.
> Once a datanode stops serving a block pool, this command can be used to
> delete the block pool directories. A force option will delete the block pool
> directory on the datanode along with all its contents. If force is not
> specified directories will be deleted only if no block files exist for that
> block pool.
