Currently, I use HDF 3.1 in Cloudbreak to deploy a cluster with NiFi and Zookeeper but I created a custom nifi-processor to get the mongo oplog, this processor needs the mongo driver 3.8 or 3.9, then:
- Current NiFi version in HDF 3.1 doesn't support this custom nifi-processor.
- Locally I test my processor with the latest version in docker hub of HortonWorks and, it's working!
I can upgrade NiFi in Cloudbreak or modify the image catalogue?
Sorry for the late response.
The easiest solution seems to be to use a recipe to upgrade NIFI during cluster install via Cloudbreak.
Hope this helps!
