      Description

      Some of the changes needed:

      • FSNameSystem.allocateBlock creates a lot of object unnecessarily to find a blockID that is unused. It should reuse the Block object created by changing the blockID and reusing the GenerationStamp.
      • InodeFile.addBlock should use System.arrayCopy instead of copying 1 at a time.
      • Some of the for loops in FSEditLog.java can be optimized. Instead of getting the edit stream length in termination condition, a local variable should be used to do the same.
