When a directory with huge number of files is deleted, the NN becomes unresponsive
----------------------------------------------------------------------------------

                 Key: HDFS-1393
                 URL: https://issues.apache.org/jira/browse/HDFS-1393
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: name-node
            Reporter: dhruba borthakur


If one deletes a directory with about 2 million files, the namenode becomes unresponsive for
close to 20 seconds. The reason being that the FSnamesystem lock is held while all the blocks/namespace-entries
are freed.
