Description

"addBlock: Moved" should be replaced with "Copied " or "lazyPersistReplica : Copied" to avoid confusion.

  static File[] copyBlockFiles(long blockId, long genStamp,
                               File srcMeta, File srcFile, File destRoot)
  {
   ... 
    if (LOG.isDebugEnabled()) {
      LOG.debug("addBlock: Moved " + srcMeta + " to " + dstMeta);
      LOG.debug("addBlock: Moved " + srcFile + " to " + dstFile);
    }
  }
