Subject [jira] Commented: (HDFS-1482) Add listCorruptFileBlocks to DistributedFileSystem (and ClientProtocol)
Date Fri, 29 Oct 2010 19:44:21 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1482?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12926428#action_12926428
] 

Suresh Srinivas commented on HDFS-1482:
---------------------------------------

FileSystem already has methods related to blocks - FileSystem#getFileBlockLocations(). Given
that we should add this to FileSystem.

Are you going to add this change to FileContext as well?

> 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).
