Alex Petrov commented on CASSANDRA-12242:
-----------------------------------------
Just tried it all. {{TriggerExecutor}} is a singleton, and classes are loaded
on startup. If jar is not there, it won't be visible, so you need to restart
your instance to load it.
> Could not create trigger
> ------------------------

> Key: CASSANDRA-12242
> URL: https://issues.apache.org/jira/browse/CASSANDRA-12242
> Project: Cassandra
> Issue Type: Bug
> Components: CQL
> Reporter: RocWay Li
> Attachments: DataTrigger.java
>
>
> I tried cassandra 2.2.6 and 3.7, both of them could not create triggers.
> It reports that the trigger class doesn't exist. But it actually does and is
> at the right directory, the conf/triggers.
> I debugged the source code, and I found that SEPWorker is used to create
> triggers, but it's thread is not a secure thread, which should be managed by
> cassandra's SecurityManager and belongs to SecurityThreadGroup.
> When security validation failed, an exception will be thrown. That's direct
> cause for creating triggers failed.
