Actually the strange thing is that the server seems to think its not in a stuck state and lets us start/stop/modify everything as though it actually terminated. Then upon restarting the nifi server whatever was still "terminating" ends up getting pushed back to the incoming queue and replayed... which surprised us initially because the processor had been ignored/stuck in that state for so long.

Hello, We recently upgraded to NiFi 1.7.0 and tried using the "terminate" function on a processor. This function never seems to work for us... we terminate the processor and it stays in the terminating state indefinitely like the screenshot below: screen-shot-2018-10-11-at-100713-am.png We can still stop/start/edit the processor when its in this state and the only way to recover it is to restart the server. If we restart the server, all the flow files that were being processed before are sent back to their incoming queue. This actually surprised us because at one point we had a processor in this state for over a week and then when we restart our server a bunch of unexpected results were processed in a way that appeared to be "out of nowhere". Has anyone else run into issues similar to this or have a fix for this? We would like to use this feature, but it seems like it can never succesfully issue an interrupt.

Hello, Are there any publicly available nifi icon files that can be downloaded? I am building an administrative tool for managing nifi clusters and other big data software, and would love to display the little nifi dropplet next the button used to manage nifi clusters but I'm not sure where I can find the icon? Best regards, David

Has there been any progress on this ticket? I couldn't tell from the link you have. This is definite a big use case for our use of NiFi. We plan to integrate our secrets management platform with NiFi by injecting static secrets into the variable registry so that our controller services never need manual password entry. However, this is not possible for us until the variable registry is able to be encrypted at rest. Is there still work being made on this front?

@Bryan Bende Thanks for the information, I was afraid that might be the case... was hoping to assign more granular access to processors via groups to our users.

Hey all, I am hoping to manage access to nifi processors... I would like to do this by choosing what processors to add or remove from the restricted processors list. Is this possible and where can I find how to do this? Thanks!

This worked for me in combination with restarted ActiveMQ... thanks!

I pulled in a large number of files into nifi using the getFile processor... I am looking to store these files in HDFS using putHDFS. The process ran overnight and didn't have any back pressure set so the queue got backed up. It seems that this is causing threads to hang when trying to start any processor. I am also unable to empty the queue... the process just hangs indefinitely at 0%. Some things I have tried so far: Restarting Server (removes hanged threads, but threads hang whenever processors are started again) Increasing Java heap size to 16g Using G1GC garbage collector Increasing swap size of queue to 40,000 since both of the backed up queues have 29,000 (8GB) - 25,000 (800MB compressed) flow files in them respectively. Does anyone have any suggestions for what I should do next? Has anyone run into this issue before? I am on nifi version 0.6.1. Thanks for you help! 🙂
