Lease reassignment is not persisted to edit log
-----------------------------------------------

                 Key: HDFS-1149
                 URL: https://issues.apache.org/jira/browse/HDFS-1149
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: name-node
    Affects Versions: 0.21.0
            Reporter: Todd Lipcon


During lease recovery, the lease gets reassigned to a special NN holder. This 
is not currently persisted to the edit log, which means that after an NN 
restart, the original leaseholder could end up allocating more blocks or 
completing a file that has already started recovery.
