Adding to what @ChethanYM said, shared traces can also arise from third party tool while connection gets closed abruptly or issue with proxy host/knox if you are using one in JDBC connection settings. If you would like more debugging on this, appending JDBC driver DEBUG logs would be helpful. To do so, add below with JDBC connection string and repro the issue , It will generate driver DEBUG logs and may give some more details about the issue.

@Rothmny  Based on what you have shared, you should be able to accomplish this with  GenerateFlowFile and ExecuteStreamCommand processors. The GenerateFlowFile processor would be configured to generate a 0 byte FlowFile and scheduled using Cron so that it creates a FlowFile on your required schedule that will then trigger the execution of the ExecuteStreamCommand processor that will execute your python script. For calling rest-api endpoints via NiFi dataflows, you could use the InvokeHTTP processor.  Since the InvokeHTTP processor does not require and inbound connection, you could just have it as first processor in a dataflows scheduled with cron as well.  Or, if the invokeHTTP is called after your script successfully executes you could trigger with the FlowFile that exited the the ExecuteStreamCommandProcessor.

@pasq  Did you know that Cloudera makes managing and deploying your MiNiFi agents easy with Cloudera Edge Management?  Our ManagementHub provides a UI to build, deploy and update the dataflow you deploy to one too many MiNiFi agents. You can create parameters for various properties like passwords to provide those at deployment time through Edge Management Check out this Video. NiFi processors with "sensitive" properties are designed to encrypt those password when written to the flow.json.gz.  Even in MiNiFi these component classes will expect that the passwords are encrypted.  The defined sensitive.props.key property value in the minifi.properties or nifi.propertes is used in the encryption/decryption of these sensitive properties stored in the flow.json.gz file.

@David26  I am not familiar with this specific processor "Plc4xListenRecordProcessor 0.12.0".   I could not find it in Apache NiFi 1.x or 2.x versions.  I could find it in Maven Central either.  Where did you download this nar that you added to your NiFi? What version of Apache NiFi are you using? You may need to reach out to the originator of this custom nar you have added to you NiFi for this processor specific query. Please help our community grow.
