Hey,
I’m trying to get NiFi to send mqtt messages to the Azure IoT Hub. The IoT Hub
uses SSL certificates, and I’m having trouble getting it working with the
publishmqtt processor. I create a StandardSSLContextService pointing the
truststore at /usr/lib/jvm/java-8-openjdk-amd64/jre/lib/security/cacerts. I
made sure (I think) that the chain was trusted by importing it manually into
the cacerts:
openssl s_client -showcerts -connect gsetest.azure-devices.net:8883 </dev/null
| sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > msft.cert
keytool -import -noprompt -trustcacerts -alias azure -file msft.cert -keystore
/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/security/cacerts -storepass changeit
When I start the processor, I immediately get the below error. This all works
when I do it manually outside of NiFi using mosquitto_pub, so I know that my
various settings (username, password, etc) are correct. Has anyone done
something similar, or can anyone offer any help here?
