Question

I am using zookeeper to get data from kafka. And here I always get data from last offset point. Is there any way to specify the time of offset to get old data?

From the Kafka documentation they say "kafka.api.OffsetRequest.EarliestTime() finds the beginning of the data in the logs and starts streaming from there, kafka.api.OffsetRequest.LatestTime() will only stream new messages. Don’t assume that offset 0 is the beginning offset, since messages age out of the log over time. "

Use the SimpleConsumerExample here: https://cwiki.apache.org/confluence/display/KAFKA/0.8.0+SimpleConsumer+Example
