Subject Kafka controlled shutdown hangs when there are large number of topics in the cluster
Date Mon, 19 Dec 2016 13:02:10 GMT

We have 9 broker instances in a kafka cluster spread across 3 linux machines. The 1st machine
has 4 broker instances. 2nd  machine has 4 broker instances and 3rd one has 1 broker instance.
 There are around 101 topics created in the cluster

We start the broker as follows
        All 4 brokers are started on first machine
        All 4 brokers are started on 2nd machine
        1 broker started on 3rd machine

After brokers were running for sometime, we try to shutdown the brokers as below
        All 4 brokers stopped on 1st machine
        4 brokers are stopped on 2nd machine---- While we do this kafka controlled shutdown

This same issue was not seen with 25 topics.

Please let us know if any solution is known to this issue
