        Since we do not indeed use the tag in our test framework, adding it to some methods is useless. Someone later may add some other tags from other library and then it becomes very confusing. A javadoc comment is better.

        Agreed ....Thanks Nicholas. I will avoid using it.

        Hi Nicholas,

        Thanks a lot for taking a look on the patch.
        I have indorporated your comments in this patch, please have a look.

        For replthread,
        o Please remove public from replthread. You may add a getReplicationThread() method in BlockManagerTestUtil for the tests.
        o Set it to final.
        o Rename it to replicationthread.
        o Change the comment to javadoc.
        i.e. declare it as following.

        /** Replication thread. */
        public final Daemon replicationthread = new Daemon(new ReplicationMonitor());

        declared replication moniter thread as
        /** Replication thread. */
        final Daemon replicationthread = new Daemon(new ReplicationMonitor());
        Also created the getReplicationThread method in BlockManagerTestUtil. So, that tests could access the replicationthread through BlockManagerTestUtil.
        I changed replicationthread as replicationThread

        For the similar reason, let's keep corruptReplicas package private and remove getCorruptReplicas().

        Added getCorruptReplicas() in BlockManagerTestUtil.
        Reason why i keep that as private is, I observed some places in code we used google's VisibleForTesting annotation tag. So, i thought to put that for accessing in tests.
        Now made it to deafult scope.

        Similarly, remove public from computeDatanodeWork and add a getter in BlockManagerTestUtil.

        changed it to deafult scope.

        Let's set replicationRecheckInterval to final

        fixed

        Add private to ReplicationMonitor class and @Override to run().

        fixed

        Remove namesystem.getBlockManager() since we are already inside BlockManager.

        //ReplicationMonitor.run().
        + namesystem.getBlockManager().processPendingReplications();

        yes fixed. i missed it ....oversight

        Remove the following comments since it is no longer valid.

        /////////////////////////////////////////////////////////
        //
        // These methods are called by the Namenode system, to see
        // if there is any work for registered datanodes.
        //
        /////////////

        cleaned the comments which are unnecessary now.

        I will take care of such comments in future. - Thanks
