Subject [jira] [Commented] (HDFS-10975) fsck -list-corruptfileblocks does not report corrupt EC files
Date Thu, 06 Oct 2016 23:00:26 GMT

    [ https://issues.apache.org/jira/browse/HDFS-10975?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15553483#comment-15553483

Wei-Chiu Chuang commented on HDFS-10975:

It is also worth noting that without any parameters, the corrupt EC file is also reported
as having an underr replicated block. An EC block should not be called under replicated if
it misses 4 "replicas".

>             Project: Hadoop HDFS
>          Issue Type: Sub-task
>    Affects Versions: 3.0.0-alpha2
>            Reporter: Wei-Chiu Chuang
> HDFS-10826 fix fsck for corrupt EC files if no parameters are specified.
> However, if I change the test case added in HDFS-10826 (TestFsck#testFsckCorruptECFile)
to run "fsck -list-corruptfileblocks", the same test test failed because fsck reports no corrupt
> Interestingly, if I run "fsck -files -blocks -replicaDetails" then the test passed and
shows the corrupt file.
> Need to fix the discrepancy.
