> Hi,
> We are trying to implement Ranger 2 .1.0 on top of AWS EMR 6.1.0.
> EMR 6.1.0 has hadoop 3. The cluster is Kerberos enabled.
> I have installed ranger in a separate ec2 machine and able to install hdfs
> plugin in EMR.
> But the problem is that for policies to be applied, both ranger server and
> hdfs namenode should be restarted . After I restart both the policies becomes
> effective
> Ranger admin logs shows below error.
