Hi All, We are currently in the process of upgrading from NiFi 1.5 to 1.8. After making the binary changes and restarting the cluster (a secure cluster setup), we are getting the following error:
ERROR [main] org.apache.nifi.encrypt.StringEncryptor * A blank sensitive properties key was provided Specify a unique key in nifi.properties for nifi.sensitive.props.key The Encrypt Config Tool in NiFi Toolkit can be used to migrate the flow to the new key. We are using all the same config that was in the 1.5 setup, including a blank key for nifi.sensitive.props.key which wasn't an issue before, but now it seems that it is. I didn't see this as a known issue in any of the migration guides or release notes. Can anyone provide any insight on this? Steps to remediate? Is the cause exactly what the error message says, having a blank value for this config prop? Cheers, Ryan H
