Subject [jira] Commented: (HDFS-1482) Add listCorruptFileBlocks to DistributedFileSystem (and ClientProtocol)
Date Mon, 01 Nov 2010 19:06:27 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1482?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12927092#action_12927092
] 

Patrick Kling commented on HDFS-1482:
-------------------------------------

The review board entry for this JIRA can be found at https://reviews.apache.org/r/18/

Couldn't we add listCorruptFileBlocks as a DFS-only method for now and add it to FileSystem
once other file systems support this operation (since it would require a separate JIRA in
HADOOP anyway)?

> 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).
