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

             Summary: Kafka spout should consume from latest when zk committed offset bigger than latest offset
                 Key: STORM-2270
                 URL: https://issues.apache.org/jira/browse/STORM-2270
             Project: Apache Storm
          Issue Type: Bug
          Components: storm-kafka
    Affects Versions: 1.0.0, 0.9.6
            Reporter: Yuzhao Chen
             Fix For: 1.0.1


Kafka spout should consume from latest when ZK offset bigger than latest offset[ an TopicOffsetOutOfRangeException thrown out ], especially when Kafka topic change it's leader and some data lost, if we consume from earliest offset, much meaningless duplicate records will be re-consumed. So, we should consume from latest offset instead.
