> Hello
> While consuming a topic with log compaction enabled, I am getting an infinite consumption
loop of the same record, i.e, each call to poll is returning to me 500 times one record (500
is my max.poll.records). I am using the java client 0.11.0.0.
> Running the code with the debugger, the initial problem come from `Fetcher.PartitionRecords,fetchRecords()`.
> Here I get a `org.apache.kafka.common.errors.CorruptRecordException: Record size is less
than the minimum record overhead (14)`
> Then the boolean `hasExceptionInLastFetch` is set to true, resulting the test block in
`Fetcher.PartitionRecords.nextFetchedRecord()` to always return the last record.
> I guess the corruption problem is similar too https://issues.apache.org/jira/browse/KAFKA-5582
but this behavior of the client is probably not the expected one
