namenode -format giving permission denied error

Postby sandip » Tue Aug 26, 2014 6:46 pm

I am getting below error when doing Namenode - format.
can't create folder, permission denied

I also tried sudo but then also it is not working. is it permission issue?
am i missing any setting in core-site.xml file?

You can overcome this limitation by using
dfs.permissions.superusergroup setting in hdfs-site.xml
Set it to a group that Accumulo is part of (any anyone else you want to have access).
Give the name of group, "hadoop" group. The default value is "supergroup".

Return to “Hadoop and Big Data”
