You are running on tip of the append branch or on cdh3 release?  If
not, you could see the above because you are missing the recover lease
short-circuit that was added to branch-0.20-append.

Otherwise it could be a peculiarity of pseudo-distributed mode w/
replica 1 (I presume).

For sure all processes are down.

Oh, in pseudo-distributed mode, the master and regionserver are
probably sharing the same hdfs user identity; so the user holding the
lease still 'exists' though the regionserver 'crashed'.
