Uma Maheswara Rao G created HDFS-4516:
-----------------------------------------

             Summary: Client crash after block allocation and NN switch before lease recovery
for the same file can cause readers to fail forever
                 Key: HDFS-4516
                 URL: https://issues.apache.org/jira/browse/HDFS-4516
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: namenode
    Affects Versions: 2.0.3-alpha, 3.0.0
            Reporter: Uma Maheswara Rao G
            Priority: Critical


If client crashes just after allocating block( blocks not yet created in DNs) and NN also
switched after this, then new Namenode will not know about locs.

Further details will be in comment.
