Tutorial

Use HBase In Different Namespace

Operation Steps

Please refer the steps below to connect the external HBase to your namespace:

1. Log in Kubernetes UI.
2. Select the namespace you want to connect to the HBase.

3. Clicks on CREATE, and UPLOAD the YAML file. The content of YAML file must includes the configuration information of zookeeper, hbase-master, and hbase-regionserver of the HBase.

   Here is an example of zookeeper configuration:

   apiVersion: v1
   kind: Service
   metadata:
    # name is the zookeeper service name in the external HBase environment. Make sure the names in the namespace are not same as the service name.
    name: zookeeper
   spec:
    ports:
    # The port for communication between the services.
    - port: 2181
      targetPort: 2181
    type: ExternalName
    # The format of externalName: 'zookeeperServiceName.theNamespaceofHBase.svc.cluster.local'.
    externalName: zookeeper.hbase-107.svc.cluster.local

4. Register HBase. Please refer to GIS Cloud Suite Documentation Storage Resources > HBase > Register HBase.

   Notes:

   When registering HBase, the format of server address is ‘zookeeperServerName:Port’, eg, zookeeper:2181.
