This behavior is configurable. There is a property in hbase-site.xml
hbase.superuser which control this behavior. Here is a snippet of that file.
<property>
<name>hbase.superuser</name>
<value>hbase</value>
<description>List of users or groups (comma-separated), who are allowed
full privileges, regardless of stored ACLs, across the cluster.
Only used when HBase security is enabled.

Subject: Re: hdfs user can bypass policy in ranger
Thanks Loïc for the quick response! So, to protect PII information being
accessed from admins encryption is the way ahead. Right?

Hi Suraj Nayak,
As Hadoop authorizations run the same way than Unix ones, hdfs is the
equivalent of super user in Linux.
So basically yes hdfs can bypass any rule/policy set by Ranger as it has all
the rights on the cluster.

Objet : hdfs user can bypass policy in ranger
Hi Ranger Users,
Am new to Ranger. What I tried was, I created a HDFS policy for a file created
by user say hdusr. The policy states only hdusr can access. Ranger behaves
perfectly well by denying access to this hdfs file resource for all users other
than hdusr except hdfs user.
Does this mean that hdfs superuser can bypass the policy and open, rename and
delete a file which is protected by Ranger policy?
Thanks in advance :)
