> Kafka Streams State stuck in rebalancing after one of the StreamThread
> encounters java.lang.IllegalStateException: No current assignment for
> partition

> Key: KAFKA-9073
> URL: https://issues.apache.org/jira/browse/KAFKA-9073
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Affects Versions: 2.3.0
> Reporter: amuthan Ganeshan
> Priority: Major
> Attachments: KAFKA-9073.log

>
> I have a Kafka stream application that stores the incoming messages into a
> state store, and later during the punctuation period, we store them into a
> big data persistent store after processing the messages.
> The application consumes from 120 partitions distributed across 40 instances.
> The application has been running fine without any problem for months, but all
> of a sudden some of the instances failed because of a stream thread exception
> saying
> ```java.lang.IllegalStateException: No current assignment for partition
> <app_name>-<store_name>-changelog-98```
>
> And other instances are stuck in the REBALANCING state, and never comes out
> of it. Here is the full stack trace, I just masked the application-specific
> app name and store name in the stack trace due to NDA.

> Now I checked the state sore disk usage; it is less than 40% of the total
> disk space available. Restarting the application solves the problem for a
> short amount of time, but the error popping up randomly on some other
> instances quickly. I tried to change the retry and retry.backoff.ms
> configuration but not helpful at all
> ```
> retries = 2147483647
> retry.backoff.ms

> After googling for some time I found there was a similar bug reported to the
> Kafka team in the past, and also notice my stack trace is exactly matching
> with the stack trace of the reported bug.
> Here is the link for the bug reported on a comparable basis a year ago.
> https://issues.apache.org/jira/browse/KAFKA-7181
>
> Now I am wondering is there a workaround for this bug though configuration
> changes, or is there something wrong the way I set up the application, the
> following are the configuration I have for my stream application.
>
> ```
> consumer.session.timeout.ms=30000
> metric.reporters=org.apache.kafka.common.metrics.JmxReporter
> replication.factor=3
> metadata.max.age.ms=30000
> max.partition.fetch.bytes=2000000
> producer.retries=2147483647
> bootstrap.servers= <bootstrap server list goes here>
> metrics.recording.level=DEBUG
> producer.retry.backoff.ms=60000
> consumer.auto.offset.reset=latest
> application.server=0.0.0.0:6063

> heartbeat.interval.ms=10000
> max.poll.interval.ms=300000
> num.stream.threads=10
> application.id= <application id goes here>
> ```
> Note: The original bug reported a year back got a conclusion that it is
> related to https://issues.apache.org/jira/browse/KAFKA-7657 and reported
> solved in version 2.2.0, but I am using the latest 2.3.0 version.
> I appreciate your help concerning this bug.
