[jira] Commented: (HADOOP-95) dfs validation

    [ http://issues.apache.org/jira/browse/HADOOP-95?page=comments#action_12431933 ] 
            
Sameer Paranjpye commented on HADOOP-95:
----------------------------------------

Is this issue still pertinent? We have an fsck utility and TestDFSIO has been committed via a separate JIRA issue.

> Dfs needs a validation operation similiar to fsck, so that we get to know the files that are corrupted and which data blocks are missing.
> Dfs namenode also needs to log more specific information such as which block is replication or is deleted. So when something goes wrong, we have a clue what has happened.
