[jira] [Created] (STORM-2357) add At-Most-Once guarantee in KafkaSpout

Xu Mingmin created STORM-2357:
---------------------------------

             Summary: add At-Most-Once guarantee in KafkaSpout
                 Key: STORM-2357
                 URL: https://issues.apache.org/jira/browse/STORM-2357
             Project: Apache Storm
          Issue Type: Bug
          Components: storm-kafka-client
            Reporter: Xu Mingmin


KafkaSpout cannot guarantee exactly at-most-once semantic, as it commits offset periodically, and KafkaSpout.close() is not guarantee to call when a crash happens.
