Facing Ranger setup and HDFS Plugin issue

[Bunny1992]

Hello Team,
I am currently stuck with a couple of issues while imitating your project. I am unable to see plugins mainly ./enable-plugin.sh file. Can you please put light on how to install plugins mainly HDFS in Ranger? Also, the Audit logs are not working because of the below issue. Please help me resolve the same.
