------------------------------------------
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.
