[jira] [Created] (HADOOP-10619) Replace BytesMoved class with AtomingLong

Benoy Antony created HADOOP-10619:
-------------------------------------

             Summary: Replace BytesMoved class with AtomingLong
                 Key: HADOOP-10619
                 URL: https://issues.apache.org/jira/browse/HADOOP-10619
             Project: Hadoop Common
          Issue Type: Improvement
    Affects Versions: 2.4.0
            Reporter: Benoy Antony
            Assignee: Benoy Antony


The Balancer internally uses a class _BytesMoved_ to keep track of the bytes moved. It has the same requirements and semantics of _AtomicLong_. But _BytesMoved_  uses monitors. It will be an improvement for Balancer to use _AtomicLong_ instead of custom class.
