> When a file/directory is removed, the namenode should repair the leases so that the existing
leases point to the  appropriate file. The lease record has the pathname of the file that
it refers to.
> This is required because the namenode has to invoke lease-recovery on the correct file
if the client that was writing to a file dies.
