@JamesZhang  Certainly a challenging issue you have here.  The shared output all points to good certificates, but gets you no closer to why the mutualTLS exchange between your two Nifi nodes is no yielding a successful mutual TLS handshake. I guess I would start by looking at the configuration of NiFi on both nodes to make sure configurations in the nifi.properties files on both nodes match.  Verify that both nodes NiFi's are using same Java version. You may need to look at the network traffic between both nodes as well.  Is there some device (load balancer, firewall, etc) between those nodes on the network that may be interfering with the certificate exchange.

@pratschavan  FetchFile is typically used in conjunction with ListFile so that it only fetches the content for the FlowFile it is passed.  ListFile would only list the file once. If you are using only the FetchFile processor, I am guessing you configured the "File to Fetch" property with the absolute path to you file.  Using this processor in this way means that it will fetch that same file every time it is scheduled to execute via the processor's "Scheduling" tab configuration. Can you share screenshots of how you have these two processors configured?

Hello, Here is the threaddump of last restart of node 2304. We took a threaddump every 5 minutes: threaddump  I notice only "Cleanup Archive for contentX" that seems take more than 5 minutes for some content repo. Don't know if this cleaning can be a blocking point. And maybe I'm missing something on the interpretation of threaddump. I take also some screens of the cluster view to check if there is more usage of the 2 bad nodes (2304 and 2311). The 2 nodes has 40GB more flowfiles (6% of usage instead of 5% for others): Screen cluster  Nifi is clustered and we have three zookeeper server nodes dedicated for Nifi. Do you know how we can check zookeeper actions: election of the Cluster and Primary role? Thanks for your help Best Regards ... View more

Thanks @MattWho . Well... I regained ownership of the Nifi platform; I don't have the information regarding the initial installation. I will check about ExecStop and give a feedback. Thanks a lot ! ... View more

@PriyankaMondal  What is being logged in the nifi-user.log when the issue happens? Have you tried using your browser's developer tools to look at the data being exchanged in the request with the NiFi cluster? Feels like maybe the site cookies are not being sent to the NiFi node after successful authentication resulting in the exception being seen. Thanks, Matt ... View more

Thank you for the advisement. I understand what you are saying. ... View more
