---------------------------------------------------------------------
[~junrao], this issue is not yet fixed it seems. We, as others here, are
experiencing the same loop replication of partitions when trying to delete
topics via the bin/kakfa-topics command using 1.1 brokers.
If fixed as you say, could someone update the exact broker version where it is
fixed?
If am torn to upgrade to 2.2 on the brokers, as this bug report does not
reflect what you imply by your "We fixed another issue" - that is, assuming the
issue is fixed - comment above.

> Key: KAFKA-2729
> URL: https://issues.apache.org/jira/browse/KAFKA-2729
> Project: Kafka
> Issue Type: Bug
> Affects Versions: 0.8.2.1, 0.9.0.0, 0.10.0.0, 0.10.1.0, 0.11.0.0
> Reporter: Danil Serdyuchenko
> Assignee: Onur Karaman
> Priority: Major
> Fix For: 1.1.0

> After a small network wobble where zookeeper nodes couldn't reach each other,
> we started seeing a large number of undereplicated partitions. The zookeeper
> cluster recovered, however we continued to see a large number of
> undereplicated partitions. Two brokers in the kafka cluster were showing this
> in the logs:
> {code}
> [2015-10-27 11:36:00,888] INFO Partition
> [__samza_checkpoint_event-creation_1,3] on broker 5: Shrinking ISR for
> partition [__samza_checkpoint_event-creation_1,3] from 6,5 to 5
> (kafka.cluster.Partition)
> [2015-10-27 11:36:00,891] INFO Partition
> [__samza_checkpoint_event-creation_1,3] on broker 5: Cached zkVersion [66]
> not equal to that in zookeeper, skip updating ISR (kafka.cluster.Partition)
> {code}
> For all of the topics on the effected brokers. Both brokers only recovered
> after a restart. Our own investigation yielded nothing, I was hoping you
> could shed some light on this issue. Possibly if it's related to:
> https://issues.apache.org/jira/browse/KAFKA-1382 , however we're using
> 0.8.2.1.
