风暴卡夫卡喷口失败

Question

i am using storm0.9.4 with storm-kafka:0.9.0-wip16a-scala292 as the dependency to read from kafka 0.7 .

• Our kafka retention policy is 7 days.
• I start reading from the latest offset of the brokers.

As soon as i start the topology within a few minutes i get the error below:

kafka.common.OffsetOutOfRangeException: null

I am not able to find why this is happening. Please provide Any help/pointers as to how do i find the problem.

Answer 1

There was a problem in the way the spout was configured. We have custom properties we use to initialize the SpoutConfig object, we set both forceFromStart and startOffsetTime(to latest) always. The problem was that the property relating to the later was configured with the wrong key and hence sometimes the zk entry for a spout was having an earlier offset entry which no longer existed in kafka or was referring to an entry present when the storm topology started but were removed from kafka before storm could finish the backlog. Since we anyways did not want to satisfy this scenario we just corrected the configuration and its working.
