Russell Bateman created NIFI-4237:
-------------------------------------
Summary: EncryptionOperationNotPossibleException in
nifi-bootstrap.log might suggest underlying cause
Key: NIFI-4237
URL: https://issues.apache.org/jira/browse/NIFI-4237
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Reporter: Russell Bateman
Priority: Minor
Fix For: 1.4.0
Our Ansible instructions upgraded NiFi and created a new
{{nifi.sensitive.props.key}}. In _nifi.properties_ this property, if extant, is
used to encrypt sensitive properties in _flow.xml.gz_. Thus, upon relaunching
NiFi, the wrong key was used to decrypt resulting in the reported failure to
start, _flow.xml.gz_ is no longer useful.
We found the problem and fixed it after Mark Payne suggested a possible cause,
but if this state of things can be determined, it might save on community
support for this situation if the logged message were to suggest what's at the
bottom of this problem. The top of the stack trace appears in
_logs/nifi-bootstrap.log_ as below:
