Redis Sink Connector error (QuickStart document)

I’d like to use redis sink connector and follow this instruction http://docs.datamountaineer.com/en/latest/redis.html but the connector error and cannot sink to redis (error below)

# kafka-avro-console-producer --broker-list localhost:9092 --topic redistopic --property value.schema='{"type":"record","name":"User","namespace":"com.datamountaineer.strea mreactor.connect.redis","fields":[{"name":"firstName","type":"string"},{"name":"lastName","type":"string"},{"name":"age","type":"int"},{"name":"salary","type":"double"}]}' SLF4J: Class path contains multiple SLF4J bindings. SLF4J: Found binding in [jar:file:/opt/confluent/share/java/kafka-serde-tools/slf4j-log4j12-1.7.6.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: Found binding in [jar:file:/opt/confluent/share/java/schema-registry/slf4j-log4j12-1.7.6.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation. SLF4J: Actual binding is of type [org.slf4j.impl.Log4jLoggerFactory] {"firstName": "John", "lastName": "Smith", "age":30, "salary": 4830}

after use kafka-avro-console-producer and input sample data the connector will fail

Task 0 is FAILED

Could you please suggest me how to solve this and how to use redis sink connector?

PS. cassandra sink work properly, I try to reconfigure/reinstall manually and try to use fast-data-dev docker https://hub.docker.com/r/landoop/fast-data-dev/ but still same error

Thank you

There is a problem with the connector. It builds the key on the transformed struct, which in this case is just containing age ( Select age from redistopic PK firstName). Until we fix this you need to add the field for your key in the Select fields. For example : select age, firstName from redistopic PK firstName

@stheppi @Antwnis Thank you for your advice, now I can sink to redis with landoop container when I added ‘PK firstName’ to kcql. I’ll reinstall production server again.

thank you so much again!!
