Subject [jira] Commented: (HDFS-1111) getCorruptFiles() should give some hint that the list is not complete
Date Mon, 03 May 2010 08:38:58 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1111?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12863268#action_12863268

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.

> 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.
