zhangwei commented on HADOOP-5019:
----------------------------------
> Security: what about having whoever has write access to the file can do it?
> This would let the owner of a file check it.
I don't think so. Given the block No,how do you know who own it before running
check?
Super user may be suitable to get the block's info.
> add querying block's info in the fsck facility

> 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 .
