We have a Nifi cluster with 3 nodes running in docker containers that are always processing something. I included keys in the truststore.jks file of each node and for the changes have effect, I need to restart each node at a time, so that Nifi could still be running and we don't lose any data . There a way to restart them safely? ChatGPT said that it's possible to execute inside the container the command nifi.sh stop, but I don't know if this will cause data loss. ... View more

Both Nifi and Nifi Registry services are configured to use LDAP, the user authentication in both of them are working just fine. The communication between Nifi and Registry is made by calling IP and Port and I use the same addresses to access their UI and login with my LDAP user. But when I try to start version control in one of the Nifi access groups it can connects to the Nifi Registry but returns "No available buckets" even with the buckets already been created in Nifi Registry. This is the Registry logs when I use the "Start version control" option inside Nifi and it can't find the buckets:     2024-10-17 17:39:54,289 DEBUG [NiFi Registry Web Server-15] o.a.n.r.w.s.a.IdentityFilter Attempting to extract user credentials using X509IdentityProvider 2024-10-17 17:39:54,290 DEBUG [NiFi Registry Web Server-15] o.a.n.r.w.s.a.x.X509CertificateExtractor No client certificate found in request. 2024-10-17 17:39:54,290 DEBUG [NiFi Registry Web Server-15] o.a.n.r.w.s.a.IdentityFilter Attempting to extract user credentials using JwtIdentityProvider 2024-10-17 17:39:54,290 DEBUG [NiFi Registry Web Server-15] o.a.n.r.s.a.BearerAuthIdentityProvider HTTP Bearer Auth credentials not present.
