the class BlockMetadataManager method moveBlockMeta.

/**
   * Moves the metadata of an existing block to another location or throws IOExceptions. Throws an

   * @param newLocation new location of the block
   * @return the new block metadata if success, absent otherwise
   * @throws BlockDoesNotExistException when the block to move is not found
   * @throws BlockAlreadyExistsException when the block to move already exists in the destination
   * @throws WorkerOutOfSpaceException when destination have no extra space to hold the block to
   *         move
