Stig Rohde Døssing commented on STORM-2994: ------------------------------------------- Great. Added you to the contributors list here, so you should be able to assign the issue to yourself now. > KafkaSpout consumes messages but doesn't commit offsets > ------------------------------------------------------- > > 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, 1.1.0, 1.1.2, 1.2.1 > Reporter: RAbreu > Priority: Major > > 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. > -- This message was sent by Atlassian JIRA (v7.6.3#76005)
