> In ReplicaManager.handleLogDirFailure(), we call 
> zkClient.propagateLogDirEvent after  logManager.handleLogDirFailure. The 
> latter closes the file handles of the offline replicas, which could take time 
> when the disk is bad. This will delay the new leader election by the 
> controller. In one incident, we have seen the closing of file handles of 
> multiple replicas taking more than 20 seconds.
