Manikumar resolved KAFKA-2343.
------------------------------
Resolution: Fixed
Javadocs updated in newer versions.
> Clarify KafkaConsumer.poll rebalance behavior
> ---------------------------------------------
>
> Key: KAFKA-2343
> URL: https://issues.apache.org/jira/browse/KAFKA-2343
> Project: Kafka
> Issue Type: Bug
> Components: consumer
> Reporter: Jason Gustafson
>
> The current javadoc for KafkaConsumer.poll says the following:
> {code}
> * The offset used for fetching the data is governed by whether or not
> {@link #seek(TopicPartition, long)} is used.
> * If {@link #seek(TopicPartition, long)} is used, it will use the
> specified offsets on startup and on every
> * rebalance, to consume data from that offset sequentially on every
> poll. If not, it will use the last checkpointed
> * offset using {@link #commit(Map, CommitType) commit(offsets, sync)}
> for the subscribed list of partitions.
> {code}
> Unless I am misreading, this suggests that rebalance should reset to the
> seeked position (if one was set). The consumer definitely doesn't do this
> currently, so we should either fix the javadoc if that is not the desired
> behavior or fix the code.
