2018-12-20 16:25:05 ERROR ...:186 - Exception caught in kafka steam while processing data: org.apache.kafka.streams.errors.StreamsException: Input record ConsumerRecord(topic = ..., partition = 1, offset = 626361563, CreateTime = -1, serialized key size = -1, serialized value size = 1779, headers = RecordHeaders(...) has invalid (negative) timestamp. Possibly because a pre-0.10 producer client was used to write this record to Kafka without embedding a timestamp, or because the input topic was created before upgrading the Kafka cluster to 0.10+. Use a different TimestampExtractor to process this data.
