Hi everyone wanted to check if somebody else has found an issue like this?,
and could maybe have some pointer or has encountered this before
my kyro serializer is failing to serialize
com.google.protobuf.UnmodifiableLazyStringList
I am tyring to read a protobuf message with the data streaming API, but
it's having issue serializing a class that has a field
repeated string redacted_of_something = 2;
serialization is being configure like this
val environment = StreamExecutionEnvironment.getExecutionEnvironment()
environment.config.enableForceAvro()
val unmodColl =
Class.forName("java.util.Collections\$UnmodifiableCollection")
environment.config.addDefaultKryoSerializer(unmodColl,
UnmodifiableCollectionsSerializer::class.java)
When I don't send the problematic field (an array of strings), everything
works fine, but when I do, the application fails. This is the stack
trace.(attached)
.....
Caused by: java.lang.NullPointerException
at
com.google.protobuf.UnmodifiableLazyStringList.size(UnmodifiableLazyStringList.java:47)
so far i have try defining custom serializer for my problematic proto buff
generate classes with
environment.config.registerTypeWithKryoSerializer(EventMetaData::class.java,
JavaSerializer::class.java) , ProtobufSerializer
inspecting the code i can see the UnmodifiableLazyStringList is the
generate class for the repeated string redacted_of_something and doesn't
have a parse method
any idea aprreciate
