Hi All,
I have a UDF/UDA that returns a map of date -> TupleValue.
CREATE OR REPLACE FUNCTION min_max_by_timestamps_udf(state map<date,
frozen<tuple<timestamp, timestamp>>>, flake blob)
RETURNS NULL ON NULL INPUT
RETURNS map<date, frozen<tuple<timestamp, timestamp>>>
LANGUAGE java
CREATE OR REPLACE AGGREGATE min_max_by_timestamps(blob)
SFUNC min_max_by_timestamps_udf
STYPE map<date, frozen<tuple<timestamp, timestamp>>>
INITCOND {};
I’ve been using the following syntax to build the TupleType/TupleValue in my
UDF:
TupleType tupleType =
TupleType.of(com.datastax.driver.core.ProtocolVersion.NEWEST_SUPPORTED,
CodecRegistry.DEFAULT_INSTANCE, DataType.timestamp(), DataType.timestamp());
tupleType.newValue(new java.util.Date(timestamp), new
java.util.Date(timestamp)));
But “randomly" I get errors like the following:
FunctionFailure: code=1400 [User Defined Function failure] message="execution
of ’testdb.min_max_by_timestamps_udf[map<date, frozen<tuple<timestamp,
timestamp>>>, blob]' failed: java.security.AccessControlException: access
denied ("java.io.FilePermission" "/etc/cassandra/logback.xml" "read”)"
Or CodecNotFoundException for Cassandra not being able to find a codec for
"map<date, frozen<tuple<timestamp, timestamp>>>”.
Is this a bug or I’m doing something wrong?
Thanks,
Drew
