Configuring and Running a Local Cluster

Overview

You will use the Cluster Management Console (CMC) to configure and start the Analytics and Loader services, creating a running, local cluster on a single node.

The CMC uses a wizard to take in the specific parameters for the services as well as parameters for supporting elements like administration and database services. See Cluster Creation Wizard Default Values for guidance.

Procedure

This procedure requires the CMC be up and running. If it is not, you can start it this way:

$ ./<incorta-install-dir>/cmc/start-cmc.sh

You will also need the CMC login credentials.

1. Sign in to the Incorta CMC.

Start a supported browser (Safari, Firefox or Chrome) and open the port to the CMC. The URL is: http://localhost:6060/cmc

Sign in to the CMC using your credentials.

2. Start the Cluster Configuration Wizard.

Click Local to gain access to the Local Environment screen and to the wizard. Click Configure to start the wizard.

3. Select the database type to use.

On the Database screen, use the pull-down to select one of Derby, MySQL or Oracle.

For the MySQL and Oracle choices, additional configuration information is required including the database URL and database username and password. Retrieve this information from your notes on installing and configuring Oracle or MySQL during the provisioning process.

For this example, select Derby.

Click Next.

4. Set the contact information and user for managing the Cluster.

On the System Admin screen, set up an account for managing Clusters.

Click Next.

5. Setup the access and resource utilization limits.

Accept the default values given. Adjust the memory size to 1-2 GB for this example.

Click Next.

6. Setup the access and resource utilization limits.

On the Loader Service screen, set up the ports and resource limits accepting the default values given. Adjust the memory size to 1-2 GB for this example.

Click Next.

7. Select Spark configuration.

Spark is necessary if you want to use Pyspark or Notebooks to create Materialized Views, however, it can use significant resources on a laptop. If you wish to configure Spark, set Mode to Bundled.

Click Next.

Accept all defaults, except, change App Executors, to 2..

8. Add and configure the Notebook tool.

Accept the defaults.

Click Next.

9. Create the cluster.

Check the Review screen to confirm the settings for the Cluster are as required.

Create the cluster by clicking Create.

Details about the cluster you have created can be seen on this screen.

The last three lines show the services that are available at this point. You should see the Analytics and Loader services as well as the Notebook service. However, they are not currently active. Click Start to bring them up. You can monitor their status by clicking the refresh button in the upper right corner of the screen.

You have now created an Incorta cluster instance running on a single node.
