>             Project: Kafka
>          Issue Type: Improvement
>          Components: replication
>    Affects Versions: 0.8.2.1
>            Reporter: Alexey Ozeritskiy
>            Priority: Major

>
> ReplicaManager flushes highwatermarks only for partitions which it recieved 
> from Controller.
> If Controller sends incomplete list of partitions then ReplicaManager will 
> write incomplete list of highwatermarks.
> As a result one can lose a lot of data during incorrect broker restart.
> We got this situation in real life on our cluster.
