Resolution: Fixed
> java.lang.IllegalStateException: Attempting to put a clean entry for key...

> Key: KAFKA-4492
> URL: https://issues.apache.org/jira/browse/KAFKA-4492
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Affects Versions: 0.10.1.0
> Reporter: Damian Guy
> Assignee: Damian Guy
> Fix For: 0.10.2.0
>
>
> This follows on from https://issues.apache.org/jira/browse/KAFKA-4311
> The exception seems to be triggered by topologies with multiple joined
> tables. As a new record arrives in one table it triggers an eviction. The
> eviction causes a flush which will trigger a join processor. These in-turn
> does a cache lookup and if the value is not in the cache, then it will be
> retrieved from the store and put in the cache, triggering another eviction.
> And so on.
> Exception reported on mailing list
> https://gist.github.com/mfenniak/509fb82dfcfda79a21cfc1b07dafa89c
> Further investigation into this also reveals that this same eviction process
> can send the cache eviction into an infinite loop. It seems that the LRU is
> broken.
