Colin Patrick McCabe created HDFS-5323:
------------------------------------------

             Summary: Remove some deadcode in BlockManager
                 Key: HDFS-5323
                 URL: https://issues.apache.org/jira/browse/HDFS-5323
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: namenode
    Affects Versions: 2.3.0
            Reporter: Colin Patrick McCabe
            Assignee: Colin Patrick McCabe
            Priority: Minor


{{BlockManager#DEFAULT_MAP_LOAD_FACTOR}} is deadcode.  It no longer does *anything* since blocks are now stored in a GSet whose size is fixed.

{{BlocksMap#blocks}} does not need to be volatile.  Whenever it is accessed, it is accessed under the {{FSNamesystem}} lock.  Furthermore, access to this data structure is not thread-safe.
