Hi All,
I am using flink-gelly and using a custom POJO type as the
VertexValue/MessageType (I am using the vertex-centric model). The POJO
contains HashMap/HashSet as members. While executing the job I am getting
following Log message.
17:50:53,582 INFO org.apache.flink.api.java.typeutils.TypeExtractor
- No fields detected for class java.util.HashSet. Cannot be used as a
PojoType. Will be handled as GenericType
17:50:53,583 INFO org.apache.flink.api.java.typeutils.TypeExtractor
- class java.util.HashMap is not a valid POJO type
Is there a way to resolve this issue?
Thanks,
Charith
