Hi,
trying to create PCollection of my custom data class but keep failing due to
the CannotProvideCoderException:
My class is declared as follows:
@DefaultCoder(SerializableCoder.class) public class Data<DataT extends
BaseData> implements Serializable {
and it fails like this:
Caused by: org.apache.beam.sdk.coders.CannotProvideCoderException: Cannot
provide coder based on value with class my.project.Data: No CoderFactory has
been registered for the class.
why it doesn't pick the coder?
thanks,Antony.
