[jira] Commented: (HDFS-1482) Add listCorruptFileBlocks to DistributedFileSystem (and ClientProtocol)

    [ https://issues.apache.org/jira/browse/HDFS-1482?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12925683#action_12925683 ] 

dhruba borthakur commented on HDFS-1482:
----------------------------------------

My vote would be to add this to ClientProtocol and DistributedFileSystem. I would not add this to FileSystem because this API is very DFS-centric. There is precedence of doing that, e.g. DistributedFileSystem.concat().

> 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).
