My stream is producing records of type Tuple2
*.toString()* output *(usr12345,{"_key":"usr12345","_temperature":46.6})*
where the key is *usr12345* and value is
*{"_key":"usr12345","_temperature":46.6}*
The *.print()* on the stream outputs the value correctly:

Hi,
I want to use t-digest by Ted Dunning (
https://github.com/tdunning/t-digest/blob/master/src/main/java/com/tdunning/math/stats/ArrayDigest.java)
on Flink.
Locally that works perfectly. But on the cluster I get the following error:
java.lang.Exception: Call to registerInputOutput() of invokab
ializationSchema<>(resultType,
resultType, env.getConfig());
FlinkKafkaProducer010.FlinkKafkaProducer010Configuration
flinkKafkaProducerConfig = FlinkKafkaProducer010.writeToKafkaWithTimestamps(
stream,
"topic",
schema,
kafkaProducerProperties);*

Thanks!
I tested the KeyedSerializationSchema and it indeed works.
I tried to use TypeInformationKeyValueSerializationSchema just to make
things a bit more automated :)

Were you able to resolve the issue?
I first thought its an JVM-version incompatibility, but this thread
