Subject [jira] [Commented] (HDFS-9231) fsck doesn't list correct file path when Bad Replicas/Blocks are in a snapshot
Date Wed, 04 Nov 2015 22:10:28 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9231?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14990546#comment-14990546

Mingliang Liu commented on HDFS-9231:
-------------------------------------

I found a findbugs warning in {{FSDirSnapshotOp}} probably brought by this patch, tracked
by [HDFS-9377]. Please close that jira if it's wrong, or review that otherwise. Thanks.

> Currently for snapshot files, {{fsck -list-corruptfileblocks}} shows corrupt blocks with
the original file dir instead of the snapshot dir, and {{fsck -list-corruptfileblocks -includeSnapshots}}
behave the same.
> This can be confusing because even when the original file is deleted, fsck will still
show that deleted file as corrupted, although what's actually corrupted is the snapshot. 
> As a side note, {{fsck -files -includeSnapshots}} shows the snapshot dirs.
