---------------------------------------------
Summary: Replacing an aggregate with a new version doesn't reset
INITCOND
Key: CASSANDRA-10840
URL: https://issues.apache.org/jira/browse/CASSANDRA-10840
Project: Cassandra
Issue Type: Bug
Components: CQL
Environment: Observed in Cassandra 2.2.4, though it might be an issue
in 3.0 as well
Reporter: Sandeep Tamhankar

CREATE FUNCTION state_group_and_sum(state map<int, int>, star_rating int)
CALLED ON NULL INPUT
RETURNS map<int, int>
LANGUAGE java
AS 'if (state.get(star_rating) == null)
state.put(star_rating, 1); else state.put(star_rating, ((Integer)
state.get(star_rating)) + 1); return state;';
CREATE FUNCTION percent_stars(state map<int,int>)
RETURNS NULL ON NULL INPUT
RETURNS map<int, int>
LANGUAGE java AS 'Integer sum = 0; for(Object k :
state.keySet()) { sum = sum + (Integer) state.get((Integer) k); }
java.util.Map<Integer, Integer> results = new java.util.HashMap<Integer,
Integer>(); for(Object k : state.keySet()) { results.put((Integer) k,
((Integer) state.get((Integer) k))*100 / sum); } return results;';
CREATE OR REPLACE AGGREGATE group_and_sum(int)
SFUNC state_group_and_sum
STYPE map<int, int>
FINALFUNC percent_stars
INITCOND {}
# View the aggregates
select * from system.schema_aggregates;
# Now update
CREATE OR REPLACE AGGREGATE group_and_sum(int)
SFUNC state_group_and_sum
STYPE map<int, int>
FINALFUNC percent_stars
INITCOND NULL
# View the aggregates
select * from system.schema_aggregates;
```
Expected result:
* The update should have made initcond null
Actual result:
* The update did not touch INITCOND.
