Adding Kafka Topic Partitions
Scenario
You can add Kafka topic partitions on the Kafka UI.

- In security mode, the user who migrates a partition must belong to the kafkaadmin user group. Otherwise, the operation fails due to authentication failure.
- In non-security mode, Kafka UI does not authenticate any operation.
Adding a Partition
- Access the Kafka UI.
- Log in to FusionInsight Manager as a user who has the permission to access the Kafka UI and choose Cluster > Services > Kafka.
If you need to perform related operations on the page, for example, creating a topic, you need to grant related permissions to the user. For details, see Kafka User Permissions.
- On the right of KafkaManager WebUI, click the URL to access Kafka UI.
- Log in to FusionInsight Manager as a user who has the permission to access the Kafka UI and choose Cluster > Services > Kafka.
- Click Topics. The topic management page is displayed.
- In the Operation column of the item to be modified, choose Action > Alter. On the displayed page, modify the topic partition.
Currently, you can only add partitions to a cluster. That is, the number of partitions after modification must be greater than the number of original partitions.
- Click OK.
