Subject [jira] [Created] (HDFS-10978) fsck reports healthy even though dfsadmin -report shows under-replicated blocks
Date Fri, 07 Oct 2016 07:30:20 GMT
Abhay Bothra created HDFS-10978:
-----------------------------------

             Summary: fsck reports healthy even though dfsadmin -report shows under-replicated
blocks
                 Key: HDFS-10978
                 URL: https://issues.apache.org/jira/browse/HDFS-10978
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: hdfs
    Affects Versions: 2.7.2
         Environment: Running hdfs 2.7.2 on Ubuntu 12.04
            Reporter: Abhay Bothra


Output of various hdfs commands is as follows:

{code:java}
fsck /
{code}
shows system as healthy.

{code:java}
dfsadmin -report 
{code}
lists 12 files as under-replicated.


{code:java}
fsck -list-corruptfileblocks / 
{code}
shows 12 files as corrupt. These files are not listed when running the 'ls' command.

This looks like an issue has also been reported on [StackOverflow|http://stackoverflow.com/questions/37776860/hadoop-namenode-under-replicated-blocks-not-found-in-fsck]
for hadoop version 2.6.4 with no resolution.
