dhruba borthakur commented on HDFS-1111:
----------------------------------------
Maybe we can have the following method:
{quote}
int getCorruptFiles(List<FileStatus> files) throws AccessControlException,
IOException;
{quote}
The call passes in an empty list. The NameNode fills up this list with the
FileStatus objects of the first 500 corrupt files. The return value of this
method is the total number of corrupted files in the system.
> getCorruptFiles() should give some hint that the list is not complete

>
> If the list of corruptfiles returned by the namenode doesn't say anything if
> the number of corrupted files is larger than the call output limit (which
> means the list is not complete). There should be a way to hint incompleteness
> to clients.
> A simple hack would be to add an extra entry to the array returned with the
> value null. Clients could interpret this as a sign that there are other
> corrupt files in the system.
> We should also do some rephrasing of the fsck output to make it more
> confident when the list is not complete and less confident when the list is
> known to be incomplete.
