Subject [jira] Updated: (HDFS-729) fsck option to list only corrupted files
Date Mon, 16 Nov 2009 08:06:42 GMT

     [ https://issues.apache.org/jira/browse/HDFS-729?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

dhruba borthakur updated HDFS-729:
----------------------------------

    Attachment: badFiles.txt

This patch allows an API to retrieve the list of files that have blocks with no valid replicas.
The blocks either have no replicas or all of their existing replicas are corrupted. This API
can be used by fsck/jsp to quickly list files that need attention.

A new call ClientProtocol.getBadFiles() is introduced. It returns a specified number of files
per invocation. It can be used by an application to iterate over all files that have bad blocks.
