Subject [jira] Commented: (HDFS-1032) Extend DFSck with an option to list corrupt files using API from HDFS-729
Date Wed, 24 Mar 2010 01:16:27 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1032?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12848995#action_12848995
] 

André Oriani commented on HDFS-1032:
------------------------------------

That is and idea, but I think the name of the option "-corruptfiles"  by itself gives the
user the wrong idea. I mean, it is intuitive to think based on the name of the option  that
it will list all the corrupted files. ( Self Remind to fix the usage help).  On HDFS-1031
I am using the expression " reported corrupt files" . It is not exactly the correct idea,
but it is very close to. " -reported-corruptfiles ? Sounds better or is it still misleading?

> HDFS-729 created a new API to namenode that returns the list of corrupt files.
> We can now extend fsck (DFSck.java) to add an option (e.g. --list_corrupt) that queries
the namenode using the new API and lists the corrupt blocks to the users.
