Currently Zeppelin Application UI interpreters in our clusters can be restarted by any user so we want to change the permissions so only Admin Team can have the privilege to restart the service. Can someone help how this can be achieved?

@lwang Thanks for the Info my question is , our current log directory paths are set as var/log/service so to change this to /hadoop/var/log/servce should we create any directories or move the current directories under /var/log or just change the Hadoop Log Dir Prefix to /hadoop/var/log in Ambari fix the issue.

Hi Can someone help me how to change the log directory paths from /var/log to /hadoop/var/log. we have HDFS, YARN, MapReduce2, Hive, Spark2, Zookeeper, Ambari Metrics and smartsense services running in our Dev Env.
