> Key: KAFKA-9872
> URL: https://issues.apache.org/jira/browse/KAFKA-9872
> Project: Kafka

> Components: core
> Affects Versions: 1.1.0, 2.0.0, 2.1.0, 2.2.0, 2.1.1, 2.3.0, 2.4.0
> Reporter: Lee chen
> Priority: Major
>
> Recently, I face a problem of a broker restart by server shutdown directly.
> when I restart the broker, I found my consumer cannot read data.
> 1,My consumer group named "0",and The partitions of __consumer_offsets is 50.
> 2,As the Calculation results of kafka. The partition of consumer "0" is in
> partition-48
> 3, kafkaConsumer belong to consumer group “0” cannot read datas ，but when I
> change to another group which not in partition-48, all consumers are back to
> normal.It seems that* the log dir of partition-48 belong to
> __consumer_offsets is damaged*.
> 4,When I check the log dir of __consumer_offsets-48，I* found so many .snap
> files. *
> 5,I found the nummber recorded in latest log file in __consumer_offsets-48
> is smaller than the nummber recorded in recovery-point-offset-checkpoint and
> replication-offset-checkpoint
> 6,I use kafka-topics.sh to describe __consumer_offsets is normal,All replica
> is be contained in ISR.
> As my understanding，If log dir is damaged， the broker may be cannot restart.
