Matt, This is not a cluster. Yes, it’s secured. Kerberos.
The thing that gets me is I can list another queue on the same graph/same processor group. --Peter From: Matt Gilman [mailto:matt.c.gil...@gmail.com] Sent: Friday, September 09, 2016 5:25 AM To: users@nifi.apache.org Subject: Re: Erroneous Queue has No FlowFiles message Peter, Thanks for the details! These will be very helpful investigating what's happening here. A couple follow-up questions... - Is this a cluster? - Is this instance secured?

I included those messages to emphasize the difference between a normal Queue List and mine. In a normal queue list the GET step includes a non-empty “flowFileSummaries” array, assuming there are FlowFiles to show. When I list my other queue, the one with 23 FlowFiles in it, I get back an array with 23 entries. Based on the JSON I’m assuming that my queue with 100,000 files in it should return 100, but instead I get 0.

This UUID is used to perform the all the operations on the queue. This UUID is active until a DELETE request is sent. Once you delete the active request, you get the message you mentioned in the logs, this is not an issue. If you check the developer panel in chrome, you will see all 3 operations, post-get-delete in succession.
