Date Thu, 10 Jul 2014 18:12:06 GMT

    [ https://issues.apache.org/jira/browse/HDFS-6663?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14057762#comment-14057762

Chen He commented on HDFS-6663:
-------------------------------

For a huge cluster, get all files' blocks information may be costly.

> A dfsadmin command that allows finding out the file and the locations given a block number
will be very useful in debugging production issues.   It may be possible to add this feature
to Fsck, instead of creating a new command.
