----------------------------------
Summary: Scripted controller services do not handle Module
Directory changes or script errors properly
Key: NIFI-7260
URL: https://issues.apache.org/jira/browse/NIFI-7260
Project: Apache NiFi
Issue Type: Bug
Components: Extensions
Reporter: Matt Burgess
Currently for all scripted controller services (ScriptedReader, e.g.) the
scripting engine (with additional classpath modules defined by the Module
Directory property) is only recreated when the Script Engine property has
changed. It should be recreated when the Module Directory property has changed
as well.
In addition, the controller service can be enabled even with an error in the
script. The controller service reports internally that it is invalid, but
becomes enabled anyway, hiding the invalid status from the user. They may also
suffer from the issue in NIFI-4968 with logging while the script is invalid.
Instead an exception should be thrown, which prevents the CS from being
enabled, then the fix from NIFI-4968 should be applied so that excessive
logging does not occur while the CS is invalid.
