------------------------------------
Resolution: Duplicate
Resolving this as a duplicate of KAFKA-7897. This will be included in 2.1.1,
which is set to release this week. Please reopen if the issue still persists.
> Some partitions are fully truncated during recovery when log.message.format =
> 0.10.2 & inter.broker.protocol >= 0.11

> Key: KAFKA-7886
> URL: https://issues.apache.org/jira/browse/KAFKA-7886
> Project: Kafka
> Issue Type: Bug
> Components: core
> Affects Versions: 0.11.0.0, 2.0.1, 2.1.0
> Environment: centos 7
> Reporter: Hervé RIVIERE
> Priority: Major
> Attachments: broker.log
>
>
> On a cluster of Kafka 2.0.1, and brokers configured with
> * inter.broker.protocol.format = 2.0
> * log.message.format.version = 0.10.2
>
> In such configuration, when a broker is restarted (clean shutdown), the
> recovery process, for some partitions, is not taking in account the high
> watermark and is truncating and re-downloading the full partition.
> Typically for brokers with 500 partitions each / 5 TB of disk usage the
> recovery process with this configuration is during up to 1 hour whereas it
> usually takes less than 10 min in the same broker when
> (inter.broker.protocol.format = log.message.format.version)
> Partitions redownloaded seems not predictable : after several restart of the
> same broker, partitions redownloaded are now always the same.
> Broker log filter for one specific partition that was redownloaded ( the
> truncate offset : 12878451349 is corresponding to the log-start-offset) :
