zhangwei updated HADOOP-5019:
-----------------------------
Attachment: HADOOP-5019-2.patch
Hi,all
I modified it based newly trunk,the implement is these:
ONLY super user or one of the user's group is super group can run "./hadoop
fsck <blockname> -getblockinfo"
If the block found , then will show STATUS: BLOCK FOUND.
else they will show BLOCK NOT FOUND ,BLOCK INVALID or PERMISSION DENIED
And add new test case : testFsckWithBlockInfo
> 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 .
