Registering custom serializers: Flink falls back to Kryo for the types that it does not handle transparently by itself. Not all types are seamlessly handled by Kryo (and thus by Flink). import org.apache.flink.api.common.cache.DistributedCache.DistributedCacheEntry; import org.apache.flink.api.common.io.FileInputFormat; import org.apache.flink.api.common.io.InputFormat; import org.apache.flink.api.common.restartstrategy.RestartStrategies; import org.apache.flink.api.common.typeinfo.BasicTypeInfo; Flink 1.12 Kryo Serialization Error: Date: Mon, 11 Jan 2021 11:49:55 GMT: Hi, I've implemented a KryoSerializer for a specific JSON type in my application as I have a bunch of UDFs that depend on a RAW('io.circe.Json') encoder being available. The implementation is rather simple.

motsatsord. public void registerType(Class type) Registers the given type with the serialization stack. If the type is eventually serialized as a POJO, then the type is registered with the POJO serializer. Apache Flink is a framework and distributed processing engine for stateful computations over unbounded and bounded data streams. Flink has been designed to run in all common cluster environments, perform computations at in-memory speed and at any scale. What I can see is that Flink tries to consume a HybridMemorySegment which contains one of these custom raw types I have and because of malformed content it receives a negative length for the byte array: image.png Content seems to be prepended with a bunch of NULL values which through off the length calculation: image.png But I still don't have the entire chain of execution wrapped mentally in my head, trying to figure it out.
