> Key: STORM-2994
> URL: https://issues.apache.org/jira/browse/STORM-2994
> Project: Apache Storm
> Issue Type: Bug
> Components: storm-kafka-client
> Affects Versions: 2.0.0, 1.1.2, 1.0.6, 1.2.1
> Reporter: Rui Abreu
> Assignee: Rui Abreu
> Priority: Major
> Labels: pull-request-available
> Fix For: 2.0.0, 1.1.3, 1.0.7, 1.2.2
>
> Time Spent: 3.5h
> Remaining Estimate: 0h
>
> A topology that consumes from two different Kafka clusters: 0.10.1.1 and
> 0.10.2.1.
> Spouts consuming from 0.10.2.1 have a low lag (and regularly commit offsets)
> The Spout that consumes from 0.10.1.1 exhibits either:
> 1- Unknown lag
> 2- Lag that increments as the Spout reads messages from Kafka
>
> In DEBUG, Offset manager logs: "topic-partition has NO offsets ready to be
> committed", despite continuing to consume messages.
> Several configuration tweaks were tried, including setting maxRetries to 1,
> in case messages with a lower offset were being retried (logs didn't show it,
> though)
> offsetCommitPeriodMs was also lowered to no avail.
> The only configuration that works is to have
> ConsumerConfig.ENABLE_AUTO_COMMIT_CONFIG=true, but this is undesired since
> we lose processing guarantees.
