hdfs fsck Permission denied

I'm running this command line to resolve the problem of corrupt HDFS FIles :

hdfs fsck /

And I get this warning :

Connecting to namenode via http://master1:50070
FSCK started by root (auth:SIMPLE) from /192.168.1.30 for path / at Mon Oct 24 05:06:23 EDT 2016
FSCK ended at Mon Oct 24 05:06:23 EDT 2016 in 1 milliseconds
Permission denied: user=root, access=READ_EXECUTE, inode="/accumulo":accumulo:accumulo:drwxr-x--x

Any help please !!

Its a permission issue.

Run this command from hadoop bin and then try again.

hadoop fs -chmod -R 777 /accumulo

To disable permission check, set the below property in hdfs-site.xml and restart your cluster

<property>
  <name>dfs.permissions</name>
  <value>false</value>
</property>

You cannot execute fsck with normal user. You should run it with hdfs as superuser

sudo -u hdfs hdfs fsck /

In the case of only accumulo, you can try below

sudo -u accumulo hdfs fsck /accumulo

You should run this command as an "hdfs" user:

sudo -u hdfs hdfs fsck /
