Subject [jira] [Commented] (HDFS-9231) fsck doesn't explicitly list when Bad Replicas/Blocks are in a snapshot
Date Wed, 21 Oct 2015 20:25:28 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9231?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14967815#comment-14967815

Xiao Chen commented on HDFS-9231:

The test failures look unrelated and passed locally.
Findbugs seems to be having problem.
Exception in thread "main" java.io.FileNotFoundException: /home/jenkins/jenkins-slave/workspace/PreCommit-HDFS-Build/patchprocess/trunkFindbugsWarningshadoop-hdfs.xml
(No such file or directory)

Pre-patch trunk findbugs is broken?

> 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.
