Hi, Does anybody give me an idea why the data is lost at the Kafka Consumer side? I use Kafka 0.8.2 and Spark (streaming) version is 1.5.2. Sometimes, I found out I could not receive the same number of data with Kafka producer. Exp) I sent 1000 data to Kafka Broker via Kafka Producer and confirmed the same number in the Broker. But when I checked either HDFS or Cassandra, the number is just 363. The data is not always lost, just sometimes... That's wired and annoying to me. Can anybody give me some reasons?
Thanks!
