Subject [jira] Commented: (HDFS-1482) Add listCorruptFileBlocks to DistributedFileSystem (and ClientProtocol)
Date Mon, 22 Nov 2010 18:41:14 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1482?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12934543#action_12934543

Hairong Kuang commented on HDFS-1482:
-------------------------------------

This looks good. One minor comment is that lastCookie needs to be updated only once in NameNode.

> As discussed in HDFS-1111, it would be beneficial for tools such as the RAID block fixer
and RAID FSCK to have access to listCorruptFileBlocks via the DistributedFileSystem (rather
than having to parse Servlet output, which could present a performance problem).
