Hi, I have 3-node Nifi cluster. Please, i would like to ask if each node of the cluster can output different results (i.e no duplicates) from one another. SCENARIO: Let say i have 10 records on a DB. If node1 output the first record, i want node2 or node3 not to output first record again. Thank you.

Thanks. I think your approach is better to push all overheads to the Oracle Db rather than NIFI. 👍

Thanks to everyone for your kind help. Eventually, i got to know that the problem is with the access policy. I got the clue from here: https://bryanbende.com/development/2016/08/30/apache-nifi-1.0.0-secure-site-to-site Thank you all.

Please, kindly help. I am trying to do Minifi - Nifi s2s communication. So, i was trying to generate a flow file(to use for minifi) on one of Secured Nifi cluster nodes. - i dropped an input port on the root canvas & connected it to putfile processor - i created a process group. I dropped tailfile processor & Remote Process Group processor inside it. - I configured RPG with the url of the root canvas I don't actually know what i am doing wrong because all my configurations seems to be good. # Site to Site properties nifi.remote.input.host=masternode nifi.remote.input.secure=true nifi.remote.input.socket.port=10000 nifi.remote.input.http.enabled=true nifi.remote.input.http.transaction.ttl=30 sec nifi.remote.contents.cache.expiration=30 secs Below are the the pics.

Hi, Please, kindly help. Use Case: Minifi should send logs to a Secured 3 Nodes Nifi Cluster; Method: I am trying to generate client certificate on one of the Nifi nodes(https://masternode:9443)to use for minifi configuration file. I ran this command: ./tls-toolkit.sh client -c masternode -D 'CN=nifiadmin, OU=NIFI' -C /tmp/minifi/ -t nifinifinifinifi ERROR: tls-toolkit.sh: JAVA_HOME not set; results may vary [main] INFO org.apache.nifi.toolkit.tls.service.client.TlsCertificateAuthorityClient - Requesting new certificate from masternode:9443 [main] INFO org.apache.nifi.toolkit.tls.service.client.TlsCertificateSigningRequestPerformer - Requesting certificate with dn CN=nifiadmin,OU=NIFI from masternode:9443 Service client error: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target Thank you.

Thanks to everyone especially @SAMSAL. I got to know it is the firewall that was blocking the communications among the ports. I tried to add those ports to firewall but no much success. When i tried to reach NIFI GUI, i ran into this error: java.net.NoRouteToHostException: No route to host (Host unreachable). So i disable the firewall & everything worked perfectly. FIRST METHOD: NO SUCCESS firewall-cmd --zone=public --permanent --add-port 9991/tcp firewall-cmd --zone=public --permanent --add-port 2888/tcp firewall-cmd --zone=public --permanent --add-port 3888/tcp firewall-cmd --zone=public --permanent --add-port 2181/tcp firewall-cmd --reload SECOND METHOD: SUCCESS systemctl stop firewalld
