Gwen Shapira commented on KAFKA-1816:
-------------------------------------

Looks fixed in 0.8.2:

```
[root@kafkaf-2 ~]# /usr/bin/kafka-topics --create --zookeeper kafkaf-1:2181/kafka --topic
test_topic --partitions 5 --replication-factor 1 --config retention.ms=3600

[root@kafkaf-2 ~]# /usr/bin/kafka-topics --describe --zookeeper kafkaf-1:2181/kafka --topic
test_topic
Topic:test_topic	PartitionCount:5	ReplicationFactor:1	Configs:retention.ms=3600

[root@kafkaf-2 ~]# /usr/bin/kafka-topics --alter --zookeeper kafkaf-1:2181/kafka --topic test_topic
--partitions 10

[root@kafkaf-2 ~]# /usr/bin/kafka-topics --describe --zookeeper kafkaf-1:2181/kafka --topic
test_topic
Topic:test_topic	PartitionCount:10	ReplicationFactor:1	Configs:retention.ms=3600
```

> If you alter a topic to increase the number of partitions then the configuration erases
the existing configs for that topic. This can be reproduces by doing the following:
> {code:none}
> $ bin/kafka-topics.sh --create --zookeeper localhost --topic test_topic --partitions
5 --config retention.ms=3600
> $ bin/kafka-topics.sh --describe --zookeeper localhost --topic test_topic
> > Topic:test_topic        PartitionCount:5        ReplicationFactor:1     Configs:retention.ms=3600
> $ bin/kafka-topics.sh --alter --zookeeper localhost --topic test_topic --partitions 10
> $ bin/kafka-topics.sh --describe --zookeeper localhost --topic test_topic
> > Topic:test_topic        PartitionCount:10        ReplicationFactor:1     Configs:
> {code}
