    Fixing KAFKA-2309

    Currently, a LeaderAndIsrRequest does not mark the isrShrinkRate if the received ISR is smaller than the existing ISR. This can happen if one of the replicas is shut down.

    $ git pull https://github.com/auradkar/kafka K-2309

> If a broker receives a LeaderAndIsr request with a shrunk ISR (say, when a follower shuts down) it needs to mark the isr shrink rate meter when it updates its ISR.
