Description

Kryo serializer is typically inefficient and we expect all Flink ML algorithms to work without using the Kryo serializer. It will be useful to validate this by disabling Kryo fallback in all Flink ML tests.

This can be done by configuring StreamExecutionEnvironment using env.getConfig().disableGenericTypes().
