Hi Team, we have installed Nifi-1.9.2, 2-node cluster in our lab and tried to test how to start the nifi processor group along with the nifi startup. Here is the following way we tried: 1. Configured nifi as a service in our lab and created the python program where it contains the curl command to start the nifi process group and given that is given in the execstartpost option Here is the service configuration file: path: /etc/systemd/system/nifi.service
[Unit] Description=Apache NiFi After=network.target [Service] Type=forking User=root Group=root ExecStart=/opt/nifi-1.9.2/bin/nifi.sh start #ExecStartPost=/usr/bin/python /root/samplecurlcode_cluster.py ExecStop=/opt/nifi-1.9.2/bin/nifi.sh stop ExecRestart=/opt/nifi-1.9.2/bin/nifi.sh restart [Install] WantedBy=multi-user.target **** Can you please suggest to us do we have any other option to start the nifi processor group along with nifi startup. or if need to proceed with the above way am getting the TimedOut Error when i execute the below command. Command: systemctl start nifi Error: — nifi.service - Apache NiFi Loaded: loaded (/etc/systemd/system/nifi.service; disabled; vendor preset: disabled) Active: failed (Result: timeout) since Mon 2020-01-06 21:21:17 IST; 2h 5min ago Process: 22236 ExecStart=/opt/nifi-1.9.2/bin/nifi_start.sh (code=killed, signal=TERM) Jan 06 21:19:47 nifi-1 systemd[1]: Starting Apache NiFi...
