DFS Scalability: high cpu usage in addStoredBlock
-------------------------------------------------

                 Key: HADOOP-1149
                 URL: https://issues.apache.org/jira/browse/HADOOP-1149
             Project: Hadoop
          Issue Type: Bug
          Components: dfs
            Reporter: dhruba borthakur


I have seen addStoredBlock() consume lots of CPU. One possible cause is that it invokes proccessOverReplicatedBlock.
The logic to find and purge over-replicated blocks can be done much less often.
