Edward Capriolo commented on CASSANDRA-6790:
--------------------------------------------
I cleaned up the tests significantly. Without this patch triggers are only
functional from batch mutation. This is a pretty small patch. The majority is
tests.
> Triggers are broken in trunk because of imutable list

> Key: CASSANDRA-6790
> URL: https://issues.apache.org/jira/browse/CASSANDRA-6790
> Project: Cassandra
> Issue Type: Bug
> Reporter: Edward Capriolo
> Assignee: Edward Capriolo
> Fix For: 2.1 beta2
>
>
> The trigger code is uncovered by any tests (that I can find). When inserting
> single columns an immutable list is created. When the trigger attempts to
> edit this list the operation fails.
> Fix coming shortly.
