Hello @moekraft,  Thanks for reaching our community.  As of now, none of the runtimes supports JDK 21.  But I see there are efforts to include support for it on newer but also on those LTS releases.  Still we do not have information to share about the estimated time, but you can be sure that Cloudera is actively checking on the supported depencies and their EOS to always have a supported version.  You should expect that in the future, before the EOS is met, Cloudera would provide support and communications.  ...

Hello @red888,  Thanks for reaching Cloudera Community, glad to have you here.  NiFi does not support HTTPS and HTTP mixed, you will need to have only one.  Is recommended HTTPS, HTTP is supported but in the newer versions due to all the security, login auth and more, is not the best idea as you will face issues like you have seen.  NiFi will use the same HTTPS listner to communicate, this is used for the UI, REST API and node protocol traffic. All of these are HTTPS requests.  About the names, you do not need to add public DNS names. The certs only need to have the SANs matching what the nodes uses to talk each other.  In K8s is usually the pods DNS or service DNS.  There is no much NiFi docs for K8s, but some are these:  https://nifi.apache.org/nifi-docs/administration-guide.html#kubernetes-clustering  https://nifi.apache.org/nifi-docs/administration-guide.html#kubernetes-configmap-cluster-state-provider  https://nifi.apache.org/nifi-docs/administration-guide.html#kubernetes-nginx-ingress-controller  https://nifi.apache.org/nifi-docs/administration-guide.html#cluster_node_properties   ...

Hello @intersoldi,  Thanks for being part of our community.  This could be an issue related to some threads blocked.  Do you see anything on the YARN application log?  On the Spark Event Log, does it always hang on the same task?  Another thing you can try is to get jstacks and review them to see if they are hanging on any specific point or step, for example, a connection or thread.  ...

Hello @AlokKumar,  The log used the Processor or Group ID, not the name.  This is because you can have multiple processor for the same one, but the ID is always unique.  On this example, the ID is: 3be575b5-019e-1000-0000-00002f93e650 The user is also reported between the [], in my case, is vafs:  2026-05-26 18:29:51,455 INFO [NiFi Web Server-36459] o.a.n.w.s.NiFiAuthenticationFilter Authentication Success [vafs] 10.129.x.x PUT https://node1.cfm-vafs.cloudera.com:8443/nifi-api/processors/3be575b5-019e-1000-0000-00002f93e650/run-status   ...

Hello @AlokKumar,  Thanks for being part of the community.  Yes, that is possible.  You should be able to search on the nifi-user.log for entries. You can either filter them by user or by processor IDs.  For example, I did some starts and stops for this processor.  By checking the log using the ID, I found this:  2026-05-26 18:29:40,582 INFO [NiFi Web Server-36464] o.a.n.w.s.NiFiAuthenticationFilter Authentication Started 10.129.x.x [<vafs><CN=node1.cfm-vafs.cloudera.com, ST=CA, C=US>] PUT https://node1.cfm-vafs.cloudera.com:8443/nifi-api/processors/3be575b5-019e-1000-0000-00002f93e650/run-status 2026-05-26 18:29:40,582 INFO [NiFi Web Server-36464] o.a.n.w.s.NiFiAuthenticationFilter Authentication Success [vafs] 10.129.x.x PUT https://node1.cfm-vafs.cloudera.com:8443/nifi-api/processors/3be575b5-019e-1000-0000-00002f93e650/run-status 2026-05-26 18:29:40,597 INFO [NiFi Web Server-33000] o.a.n.w.s.NiFiAuthenticationFilter Authentication Started 10.129.x.x [<vafs><CN=node1.cfm-vafs.cloudera.com, ST=CA, C=US>] PUT https://node1.cfm-vafs.cloudera.com:8443/nifi-api/processors/3be575b5-019e-1000-0000-00002f93e650/run-status 2026-05-26 18:29:40,598 INFO [NiFi Web Server-33000] o.a.n.w.s.NiFiAuthenticationFilter Authentication Success [vafs] 10.129.x.x PUT https://node1.cfm-vafs.cloudera.com:8443/nifi-api/processors/3be575b5-019e-1000-0000-00002f93e650/run-status ... 2026-05-26 18:29:51,454 INFO [NiFi Web Server-36459] o.a.n.w.s.NiFiAuthenticationFilter Authentication Started 10.129.x.x [<vafs><CN=node1.cfm-vafs.cloudera.com, ST=CA, C=US>] PUT https://node1.cfm-vafs.cloudera.com:8443/nifi-api/processors/3be575b5-019e-1000-0000-00002f93e650/run-status 2026-05-26 18:29:51,455 INFO [NiFi Web Server-36459] o.a.n.w.s.NiFiAuthenticationFilter Authentication Success [vafs] 10.129.x.x PUT https://node1.cfm-vafs.cloudera.com:8443/nifi-api/processors/3be575b5-019e-1000-0000-00002f93e650/run-status 2026-05-26 18:29:51,465 INFO [NiFi Web Server-36510] o.a.n.w.s.NiFiAuthenticationFilter Authentication Started 10.129.x.x [<vafs><CN=node1.cfm-vafs.cloudera.com, ST=CA, C=US>] PUT https://node1.cfm-vafs.cloudera.com:8443/nifi-api/processors/3be575b5-019e-1000-0000-00002f93e650/run-status 2026-05-26 18:29:51,465 INFO [NiFi Web Server-36510] o.a.n.w.s.NiFiAuthenticationFilter Authentication Success [vafs] 10.129.x.x PUT https://node1.cfm-vafs.cloudera.com:8443/nifi-api/processors/3be575b5-019e-1000-0000-00002f93e650/run-status Also, by checking the ID for a proccessor group I see the following:  2026-05-26 18:31:40,166 INFO [NiFi Web Server-36460] o.a.n.w.s.NiFiAuthenticationFilter Authentication Started 10.129.x.x [<vafs><CN=node1.cfm-vafs.cloudera.com, ST=CA, C=US>] PUT https://node1.cfm-vafs.cloudera.com:8443/nifi-api/process-groups/658e5692-019e-1000-ffff-ffff8f55b0de 2026-05-26 18:31:40,167 INFO [NiFi Web Server-36460] o.a.n.w.s.NiFiAuthenticationFilter Authentication Success [vafs] 10.129.x.x PUT https://node1.cfm-vafs.cloudera.com:8443/nifi-api/process-groups/658e5692-019e-1000-ffff-ffff8f55b0de 2026-05-26 18:31:40,187 INFO [NiFi Web Server-36459] o.a.n.w.s.NiFiAuthenticationFilter Authentication Started 10.129.x.x [<vafs><CN=node1.cfm-vafs.cloudera.com, ST=CA, C=US>] PUT https://node1.cfm-vafs.cloudera.com:8443/nifi-api/process-groups/658e5692-019e-1000-ffff-ffff8f55b0de 2026-05-26 18:31:40,188 INFO [NiFi Web Server-36459] o.a.n.w.s.NiFiAuthenticationFilter Authentication Success [vafs] 10.129.x.x PUT https://node1.cfm-vafs.cloudera.com:8443/nifi-api/process-groups/658e5692-019e-1000-ffff-ffff8f55b0de This should give you the information you want.  ...
