Subject [jira] Commented: (HDFS-1403) add -truncate option to fsck
Date Thu, 23 Sep 2010 04:27:33 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1403?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12913899#action_12913899

dhruba borthakur commented on HDFS-1403:

It is possible that we make the "fsck -truncate" only cleanup files only those files whose
last modtime is within the last hour or so. I am a little worried that otherwise it might
erroneously cleanup files that do nto need fixing.

> When running fsck, it would be useful to be able to tell hdfs to truncate any corrupt
file to the last valid position in the latest block.  Then, when running hadoop fsck, an admin
can cleanup the filesystem.
