My guess would be it’s due to the UDF sandbox whitelist/blacklist ( https://github.com/apache/cassandra/blob/5288d434b3b559c7006fa001a2dc56f4f4b2e2c3/src/java/org/apache/cassandra/cql3/functions/UDFunction.java ).
As far as I’m aware there is no way current of avoiding this (other than recompiling C* with a new whitelist I guess). There is a JIRA for non-sandboxed UDFs: https://issues.apache.org/jira/browse/CASSANDRA-9892 Cheers Ben On Wed, 8 Jun 2016 at 01:07 Brian Kelly <brianke...@sgi.com> wrote: > Hi, all, > > I am attempting write a trigger that depends on a native library.
