@Scharan It seems that there is a issue with the HBASE MASTER, because we are getting the following message when we try to check the master-status by using the URL:  http://xx-xxx-xx-xx04.xxxxx.xx:61310/master-status   HTTP ERROR 500 Problem accessing /master-status.

If you have integrated your AD with zeppelin the make sure the role mapping has done correctly and you have the correct user/group defined in the shiro roles section. ... View more

@wbivp    I created a community article long ago that details the Ranger based "NiFi Resource Identifier" policy strings you would use in Ranger to provide various levels of authorization within NiFi. https://community.cloudera.com/t5/Community-Articles/NiFi-Ranger-based-policy-descriptions/ta-p/246586 For example, it you want to grant access so that users can access and create components within a PG: /process-groups/<uuid of PG> .  Grant Read and Write for your "group" and/or "user" to allow them to view configurations and added components (processors, controller services, child PGs, etc...) within this PG /data/process-groups/<uuid of PG> Granting Read and Write for your "group" and/or "user" to allow user to view and delete content (flowfiles) queued within connection within this PG. Keep in mind that child PGs will inherit the access granted to the parent PG unless explicit policies have been set on the child PG. Hope this helps, Matt ... View more
