Hello @karsten, I think this is what you are looking for: https://docs.cloudera.com/cfm-operator/2.11.0/configure-nifi-cr/topics/cfm-op-configure-nifi-cricustom-nar-providers.html There you can see the steps on how to configure a custom NAR for CDF on Kubernetes Operator. Let me know if that helps.

Hello @KMrunal, Thanks for being part of Cloudera Community. I will try to answer your questions: 1. What is the exact reason for deprecating and removing InvokeGRPC in NiFi 2.x? Answer: This was done because those processors were not really well maintened, so there was some tech debt that was not easy to solve. That is explained on https://issues.apache.org/jira/browse/NIFI-12069 and https://issues.apache.org/jira/browse/NIFI-12071 2. If we take a fork of the NiFi 1.21 gRPC NAR and use it in NiFi 2.6.0, will that work? Answer: That may work if you take the fork and rebuild it for NiFi 2.6.0. Now, this can cause problems due to dependencies, such as Netty, that is also documented here: https://issues.apache.org/jira/browse/NIFI-12367 And of course, there can be CVEs that are not solved because the processor was not properly maintained on those versions. 3. Is there an alternative recommended approach for gRPC integration in NiFi 2.x? Answer: per the context, I understand you're using standalone NiFi implementation, not CFM from Cloudera. ExecuteScript can be used. There is no specific alternatives offered, and tell to use custom processors: https://nifi.apache.org/docs/nifi-docs/components/org.apache.nifi/nifi-grpc-nar/1.5.0/org.apache.nifi.processors.grpc.InvokeGRPC/index.html Checking the CDF from Cloudera, we do offer InvokeGRPC in our CFM 4.11.0: https://docs.cloudera.com/cfm/4.11.0/release-notes/topics/cfm-supported-processors.html That version includes NiFi 2.4.0. So that could be an option if you use CDF.

Hello @zzzz77, That happens because NiFi 2.x API does not work with an empty POST on for provenance, it always needs to consume a valid JSON: https://nifi.apache.org/docs/nifi-docs/rest-api/#provenance You need to add the query, something like this: curl --insecure -X POST -H "Authorization: Bearer <token>" -H "Content-Type: application/json" -d "{\"provenance\":{\"request\":{\"maxResults\":1000}}}" https://localhost:8443/nifi-api/provenance Check in your environment.

Hello @zzzz77, The best way here should be the NiFi API. It's safer and more standardized. Also, since it's NiFi provided, it's easier to integrate. https://nifi.apache.org/docs/nifi-docs/rest-api/index.html You can use the Processors options.

Hello @Samya, Thanks for joining our community. That issue is happening because JSON_STORE format is VARCHAR(2), not VARIANT as required. Something you can try is to add a ConvertRecord processor before the PutDatabaseRecord. There, you can use a JsonTreeReader → JsonRecordSetWriter to reformat the content. In that way, the JSON_STORE field becomes a proper JSON object. Something like this👆

Yes, you're right, that is public cloud. I do not know why that environment cannot be chosen. What I think is that some prerequisites or compatibility issues. Maybe you can check here: https://docs.cloudera.com/data-engineering/cloud/release-notes/topics/cde-dl-compatibility.html

Hello @Navaneeth, Thanks for being part of Cloudera Community and using CDE. Hope we can help you. So the main issue here is that you're not able to enable the service because there is no environments available on the dropdown. Do you already have environments created? They need to be created before you can enable the service and then create the VC. Did you follow the steps here to register the environments? https://docs.cloudera.com/management-console/1.5.5/private-cloud-environments/topics/mc-private-cloud-environments.html

Hello @PeterKa, Thanks for reaching our Community. For this, JOLT always need to have the values, it's not very much flexible if an expected value is missing. But, something that JOLT offers is the default operation, that may help you to add "{"data": if it is already included. You can see it here: https://lucabiscotti.github.io/jolt-guide.github.io/#default That option may help you to have the needed format always before the shift.

Hello @enguias, Sometimes this error could be for an old algorithm such as SHA-1. And most possible if using Java 11 that is more strict with the policies. One option is to use connection without TLS, if possible and acceptable in your environment: jdbc:sqlserver://<host>:<port>;databaseName=<DB>;encrypt=disable Or, update the certificate to SHA-256 with TLS 1.2. This is the best option if you prefer to maintain the encryption. Maybe this documentation from SQL can help too: https://learn.microsoft.com/en-us/sql/database-engine/configure-windows/configure-sql-server-encryption?view=sql-server-ver17
