Paulo Motta commented on CASSANDRA-10819: ----------------------------------------- Is this fixed? Trying the following example from [here|http://www.doanduyhai.com/blog/?p=1876]: {noformat} CREATE OR REPLACE FUNCTION cumulateCounter(state map<text,bigint>, category text, count counter) RETURNS NULL ON NULL INPUT RETURNS map<text,bigint> LANGUAGE java AS ' if(state.containsKey(category)) { state.put(category, state.get(category) + count); } else { state.put(category, count); } return state; '; {noformat} On trunk still gives: {noformat} InvalidRequest: code=2200 [Invalid query] message="Could not compile function 'bla.cumulatecounter' from Java source: org.apache.cassandra.exceptions.InvalidRequestException: Java source compilation failed: Line 3: The operator + is undefined for the argument type(s) Object, long Line 5: Type safety: The method put(Object, Object) belongs to the raw type Map. References to generic type Map<K,V> should be parameterized Line 7: Type safety: The expression of type Map needs unchecked conversion to conform to Map<String,Long> {noformat} > Generic Java UDF types > ---------------------- > > Key: CASSANDRA-10819 > URL: https://issues.apache.org/jira/browse/CASSANDRA-10819 > Project: Cassandra > Issue Type: Improvement > Components: CQL > Reporter: Robert Stupp > Assignee: Robert Stupp > Priority: Minor > Labels: UDF, doc-impacting > Fix For: 3.4 > > > At the moment we only generate raw type signatures for Java UDF methods. E.g. > a CQL argument type {{map<int, text>}} is just mapped to {{java.util.Map}} > but could be mapped to {{java.util.Map<Integer, String>}}. > It's a probably simple but nice improvement and feels to be a LHF. > Depending on the complexity it might be doable for 3.0.x, too. > Thanks for the heads-up, [~doanduyhai]! -- This message was sent by Atlassian JIRA (v6.3.4#6332)
