Looks good overall.

Just curious, changes in https://github.com/apache/incubator-gobblin/pull/2745/files change the Extract constructor but seems it is not working as expected. Can you help me understand the reason briefly ?

@autumnust
Here is the original logic. You have an empty SourceState.
public Extract(TableType type, String namespace, String table) {
this(new SourceState(), type, namespace, table);
}
