 * add them to {@link #invalidateBlocks} so that they could be further
 * deleted from the respective data-nodes,
 * and remove the block from corruptReplicasMap.
 * <p>
 * This method should be called when the block has sufficient
 * number of live replicas.
 *
 * @param blk Block whose corrupt replicas need to be invalidated
 */
