----------------------------------
Summary: Uploaded NAR hits Error and stays Installing
Key: NIFI-13757
URL: https://issues.apache.org/jira/browse/NIFI-13757
Project: Apache NiFi
Issue Type: Bug
Reporter: Bryan Bende
Assignee: Bryan Bende
The NarInstallTask has a try/catch for Exception, but in some cases attempting
to load the actual extension class may produce a sub-class of Error which is
not caught but the task, so then the state never gets updated to FAILED and the
error message never gets set.
In addition, at the point during which it hits the Error, the NAR has already
been registered in ExtensionManager, and future calls to get available
extension types will see the bundle and attempt to access the extension
definitions, which also encounters the same Error and fails the overall
request. This should be made more lenient to still allow all the other
available extensions to be returned.
