Hi,
I have installed Hadoop 1.0 using .deb package.
I tried to configure superuser groups but it somehow fail. I do not know
what's wrong:
I expect root to be able to run hadoop dfsadmin -report command.
# id hdfs
uid=201(hdfs) gid=201(hdfs) groupes=123(hadoop),201(hdfs)
# id root
uid=0(root) gid=0(root) groupes=123(hadoop),0(root)
Both my hdfs user (superuser by default) and my root user are in group
hadoop.
In hdfs-site.xml I have:
<property>
<name>dfs.permissions.superusergroup</name>
<value>hadoop</value>
<description>The name of the group of super-users.</description>
</property>
I tried running refreshServiceAcl and
refreshSuperUserGroupsConfiguration as hdfs, but I still have the error:
root# hadoop dfsadmin -report
report: org.apache.hadoop.security.AccessControlException: Access denied
for user root. Superuser privilege is required
Has anyone an idea?
Thanks!
Olivier
