-----------------------------------
Summary: NiFi does not start in cluster mode without sensitive key
explicitly defined
Key: NIFI-5540
URL: https://issues.apache.org/jira/browse/NIFI-5540
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 1.7.1
Reporter: Andy LoPresto
Assignee: Andy LoPresto
While the docs instruct users to explicitly set a value for
{{nifi.sensitive.props.key}} in *nifi.properties* to use when encrypting
sensitive component properties to persist in the *flow.xml.gz*, some users do
not. Historically, these instances use a default, hardcoded key generation
value.
During the deprecation of {{StringEncryptor.createEncryptor(NiFiProperties)}}
in NIFI-5376, the code which provided the default was missed in a specific
cluster scenario.
The default should be provided, and a warning should be printed to the app log
if the provided key value is empty, in both standalone and cluster modes.
