Swapnil Ghike updated KAFKA-828:
--------------------------------

    Attachment: kafka-828-v3.patch

Actually since preferred replica election is not a heavy weight operation like 
partition reassignment (where we need to wait until the new followers catch up 
etc), we can move reading of the 
controllerContext.partitionsUndergoingPreferredReplicaElection to inside the 
controllerLock. Attached patch v3.
                
> Preferred Replica Election does not delete the admin path on controller 
> failover
