Francois Visconte updated KAFKA-17184:
--------------------------------------
Priority: Critical (was: Major)
> Remote index cache noisy logging
> --------------------------------
>
> Key: KAFKA-17184
> URL: https://issues.apache.org/jira/browse/KAFKA-17184
> Project: Kafka
> Issue Type: Bug
> Reporter: Francois Visconte
> Priority: Critical
>
> We have a tiered storage cluster where some consumers are constantly lagging
> behind.
> On this cluster, we get a ton of error logs and fail fetches with the
> following symptom:
> {code:java}
> java.lang.IllegalStateException: This entry is marked for cleanup
> at
> org.apache.kafka.storage.internals.log.RemoteIndexCache$Entry.lookupOffset(RemoteIndexCache.java:569)
> at
> org.apache.kafka.storage.internals.log.RemoteIndexCache.lookupOffset(RemoteIndexCache.java:446)
> at
> kafka.log.remote.RemoteLogManager.lookupPositionForOffset(RemoteLogManager.java:1445)
> at kafka.log.remote.RemoteLogManager.read(RemoteLogManager.java:1391)
> at kafka.log.remote.RemoteLogReader.call(RemoteLogReader.java:62)
> at kafka.log.remote.RemoteLogReader.call(RemoteLogReader.java:31)

> java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:635)
> at java.base/java.lang.Thread.run(Thread.java:840)
> {code}
> I believe this should be handled differently:
> * Log should be warn or info
> * We should reload the index when an offset is requested and the entry is
> marked for cleanup.
> We do use the default setting for
> {{remote.log.index.file.cache.total.size.bytes}} (1GiB).
