             Summary: Correct declarations of Atomic* fields from 'volatile' to 'final'
                 Key: HBASE-10693
                 URL: https://issues.apache.org/jira/browse/HBASE-10693
             Project: HBase
          Issue Type: Improvement
          Components: io, master
            Reporter: Feng Honghua
            Assignee: Feng Honghua
            Priority: Minor


By checking the usage of these Atomic* fields, they themselves don't change once being assigned to referencing an Atomic* object, so 'final' rather than 'volatile' is more proper.
On the other hand, the 'value' encapsulated in Atomic* is already declared 'volatile', while guarantees to perform correctly in multi-threads scenarios.
