Hi, So, our Streaming Job fails with the following errors. If you see the errors below, they are all related to Kafka losing offsets and OffsetOutOfRangeException.
What are the options we have other than fixing Kafka? We would like to do something like the following. How can we achieve 1 and 2 with Spark Kafka Direct? 1.Need to see a way to skip some offsets if they are not available after the max retries are reached..in that case there might be data loss. 2.Catch that exception and somehow force things to "reset" for that partition And how would it handle the offsets already calculated in the backlog (if there is one)? 3.Track the offsets separately, restart the job by providing the offsets. 4.Or a straightforward approach would be to monitor the log for this error, and if it occurs more than X times, kill the job, remove the checkpoint directory, and restart.
