[jira] [Created] (CASSANDRA-13399) java.lang.AssertionError: null
PAF created CASSANDRA-13399:
-------------------------------
Summary: java.lang.AssertionError: null
Key: CASSANDRA-13399
URL: https://issues.apache.org/jira/browse/CASSANDRA-13399
Project: Cassandra
Issue Type: Bug
Components: CQL
Reporter: PAF
When creating the following user defined AGGREGATION and FUNCTION:
CREATE FUNCTION state_group_and_total(state map<uuid, int>, type uuid)
RETURNS NULL ON NULL INPUT
RETURNS map<uuid, int>
LANGUAGE java AS '
Integer count = (Integer) state.get(type);
count = (count == null ? 1 : count + 1);
state.put(type, count);
return state;
';
CREATE OR REPLACE AGGREGATE group_and_total(uuid)
SFUNC state_group_and_total
STYPE map<uuid, int>
INITCOND {};
And creating a statement like:
SELECT group_and_total("id") FROM mytable;
When mytable is empty creates the following assertion
ERROR [Native-Transport-Requests-1] 2017-04-03 07:25:09,787 Message.java:623 - Unexpected exception during request; channel = [id: 0xd7d9159b, L:/172.19.0.2:9042 - R:/172.19.0.3:43444]
