NiFi Boot Error

[Bimal Mehta <bi...@gmail.com>]

I recently upgraded to NiFi 1.9.0.
However on starting the NiFi service I get the following error

A blank sensitive properties key was provided
Specify a unique key in nifi.properties for nifi.sensitive.props.key

I am not sure about this property. What do I need to do?

Thanks

Bimal, 

The sensitive keys property specifies a raw value from which the encryption key for sensitive component properties is derived. This is used to protect things like a database password, AWS credentials, etc. that you configure in your flows when they are persisted to the file system. You should populate this property with a long and unique value in your nifi.properties file. 

This is documented in the Admin Guide [1][2]. If you have an existing flow with sensitive properties already encrypted using the default empty key, you can migrate them using the NiFi Encrypt Config Toolkit [3].
