> This issue is about forward porting from branch-0.20-append the little namenode api that facilitates stealing of a file's lease.  The forward port would be an adaption of hdfs-1520 and its companion patches, hdfs-1555 and hdfs-1554, to suit the TRUNK.
> Intent is to get this fix into 0.22 time willing; i'll run a vote to get ok on getting it added to branch.  HBase needs this facility.
