>   Original Estimate: 24h
>  Remaining Estimate: 24h
> As now the fsck can do pretty well,but when the developer happened to the log such Block
blk_28622148 is not valid.etc
> We wish to know which file and the datanodes the block belongs to.It  can be solved by
running "bin/hadoop fsck -files -blocks -locations / | grep <blockid>" ,but as mentioned
early in the HADOOP-4945 ,it's not an effective way in a big product cluster.
> so maybe we could do something to let the fsck more convenience .
