Configuration

This section describes how to configure the Kafka REST Proxy for HPE Data Fabric Streams.

You can set these configuration parameters in the kafka-rest.properties file. The Control System displays information about the Kafka REST Proxy for the HPE Data Fabric Streams service. By default, the service runs on port 8082.

To install the Kafka REST Proxy, see Installing HPE Data Fabric Streams Tools.

To configure the Kafka REST Proxy for HPE Data Fabric Streams, edit the following file:

/opt/mapr/kafka-rest/kafka-rest-<version>/config/kafka-rest.properties

To view the Kafka REST Proxy for HPE Data Fabric Streams log files, see the following location:

/opt/mapr/kafka-rest/kafka-rest-<version>/logs/kafka-rest.log

NOTE

After installation, Warden automatically detects the configuration and starts the service. To configure the Kafka REST Proxy for HPE Data Fabric Streams, stop the service, configure the parameters, and restart the service. To stop and restart services, see maprcli node services. For example:

maprcli node services -name kafka-rest -action stop

https://<host>:8443/rest/node/services?name=kafka-rest&action=stop&nodes=<node_names>

where node_names is the node on which to perform the action; either a list of nodes, or a filter that matches a set of nodes .
