> As describe in MAPREDUCE-7082, when the block is missing, then will throw this exception, but my cluster had no missing block.
> In this example, I found getListing return location information. When block report of observer is delayed, will return the block without location.
> HDFS-13924 is introduce to solve this problem, but only consider getBlockLocations.
> In observer node, all method which may return location should check whether locations is empty or not.
