Want to add the following note. This issue could potentially happen with
non-compacted topics also. We had multiple topologies getting stuck due to this
issue including a topic with "delete" config. Based on the learnings from the
debugging myself and @vivekmittal did, even "delete" topics could encounter
this issue under the following circumstance
- A Kafka topic with relatively short retention period
- A Storm topology that consumes from such a topic with a slow processing
rate
- A fallback strategy to earliest offset OR uncommitted_earliest
Given the above, it is possible that while the spout/consumer is busy
processing messages fetched from a particular partition, the async cleaner has
run and cleaned up expired logs on the Kafka broker managing that partition.
Now when the spout fetches the next batch during a subsequent poll it is likely
to see message offsets that are not sequential to the ones it received in the
previous batch.
