[jira] [Created] (HDFS-6511) BlockManager#computeInvalidateWork() could do nothing

Juan Yu created HDFS-6511:
-----------------------------

             Summary: BlockManager#computeInvalidateWork() could do nothing
                 Key: HDFS-6511
                 URL: https://issues.apache.org/jira/browse/HDFS-6511
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Juan Yu
            Assignee: Juan Yu
            Priority: Minor


BlockManager#computeInvalidateWork() uses a for loop to check certain number of DNs to do invalidation work. but it's possible that a DN has nothing to invalidate.  
computeInvalidateWork() should loop until really invalidate certain number of DNs.
