Hi all,

In the WEB UI NFI, I can find where modifie the policies to have permission to list/empty queue

thanks for help.

@mayki wogno

In order to list a queue you need the "view the data" policy.

in order to empty a queue you need the "modify the data" policy.

If you are working with a NiFi cluster, all your nodes in the cluster will also need to be granted these policies as well.

Click on the key in the "operate" window to the left of the Canvas:

Then select the two policies listed above (Click override if you want to create a new policy and not edit the parent policy that is inherited). Add the Cluster node users and any other users you want to have those abilities.

Thanks,

Matt

Is [email protected] part of your "Admin NiFi" user group?

Did you grant "Admin Group" the "modify the data" policy?

You can set DEBUG in you logback.xml file for the following line to get more output in your nifi-users.log:

No nifi restarts are needed for any changes to the logback.xml file to take affect.

Following what Bryan Bende mentioned (in the case of a cluster),

You need to make sure all cluster nodes are a part of the policy. In my case, I created a new Group 'Cluster' and added all the nodes in this group. Then I went ahead and added this Group to a processor group (added this group for pilicies: view the data and modify the data)
