Subject [jira] [Updated] (HDFS-9231) fsck doesn't explicitly list when Bad Replicas/Blocks are in a snapshot
Date Fri, 23 Oct 2015 17:24:27 GMT

     [ https://issues.apache.org/jira/browse/HDFS-9231?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Xiao Chen updated HDFS-9231:
----------------------------
    Description: 
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.

  was:
For snapshot files, fsck shows corrupt blocks with the original file dir instead of the snapshot
dir.
This can be confusing since even when the original file is deleted, a new fsck run will still
show that file as corrupted although what's actually corrupted is the snapshot. 

This is true even when given the -includeSnapshots option.
