-------------------------------

             Summary: deltastreamer set auto.offset.reset=latest can't consume 
data
                 Key: HUDI-1006
                 URL: https://issues.apache.org/jira/browse/HUDI-1006
             Project: Apache Hudi
          Issue Type: Bug
          Components: DeltaStreamer
            Reporter: liujinhui
            Assignee: liujinhui
             Fix For: 0.6.0


org.apache.hudi.utilities.sources.JsonKafkaSource#fetchNewData


if (totalNewMsgs <= 0) {
 return new InputBatch<>(Option.empty(), lastCheckpointStr.isPresent() ? 
lastCheckpointStr.get() : "");
}

I think it should not be empty here, it should be 

if (totalNewMsgs <= 0) {
 return new InputBatch<>(Option.empty(), lastCheckpointStr.isPresent() ? 
lastCheckpointStr.get() : CheckpointUtils.offsetsToStr(offsetRanges));
}
