Igor Soarez commented on KAFKA-9837:
------------------------------------

I've put together a proposal to associate partition replicas to log directories 
in the cluster metadata and handle log directory failures without having to 
send any large request enumerating all topic partitions in a log directory. 
Please have a look [~cmccabe] and [~dengziming]

>  For the bridge release, brokers should no longer use ZooKeeper to notify the 
> controller that a log dir has failed. It should instead use an RPC mechanism.
