Samael Bate updated FLINK-32237:
--------------------------------
Description:
Because of the shaded Jackson packages having their package names prefixed,
such as
{_}org.apache.flink.shaded.jackson2.com.fasterxml.jackson.databind.json.JsonMapper{_},
when writing a Flink project in Kotlin I am unable to register the
_KotlinModule_ or use {_}jacksonObjectMapper(){_}.
It would be great if these classes were repackaged using the same using the
same _org.apache.flink.shaded.jackson2.*_ prefix:
{code:java}
import com.fasterxml.jackson.module.kotlin.KotlinModule
import com.fasterxml.jackson.module.kotlin.jacksonMapperBuilder
import com.fasterxml.jackson.module.kotlin.jacksonObjectMapper {code}
Due to the mismatch in package names I can do neither of the following:
{code:java}
val jsonMapper = jacksonMapperBuilder()
.addModule(JavaTimeModule())
.build() {code}
or
{code:java}
val jsonMapper = JsonMapper()
.registerModule(KotlinModule()) {code}
the Kotlin module inherits from {{com.fasterxml.jackson.databind.Module}} and
the re-packaged ones are inheriting from
{{{}[org.apache.flink.shaded.jackson2.com|http://org.apache.flink.shaded.jackson2.com/]{}}}{{{}.fasterxml.jackson.databind.Module{}}}.
For now I can work around this with a wrapper class but it would be nice to
have this available out of the box.

This has been the only issue I've found that prevents me from using Kotlin to
develop my Flink projects
