[jira] [Updated] (KAFKA-1816) Topic configs reset after partition
increase
[ https://issues.apache.org/jira/browse/KAFKA-1816?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andrew Jorgensen updated KAFKA-1816:
------------------------------------
Description:
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}
