Installation

Install the Stackable HDFS operator and its dependency, the Zookeeper operator, as well as the commons, secret and listener operators which are required by all Stackable operators.

There are multiple ways to install the Stackable operators. stackablectl is the preferred way, but Helm is also supported. OpenShift users may prefer installing the operator from the RedHat Certified Operator catalog using the OpenShift web console.

  • stackablectl

  • Helm

stackablectl is the command line tool to interact with Stackable operators and our recommended way to install operators. Follow the installation steps for your platform.

After you have installed stackablectl, run the following command to install all operators necessary for the HDFS cluster:

stackablectl operator install \
  commons=24.11.1-rc1 \
  secret=24.11.1-rc1 \
  listener=24.11.1-rc1 \
  zookeeper=24.11.1-rc1 \
  hdfs=24.11.1-rc1

The tool prints

Installed commons=24.11.1-rc1 operator
Installed secret=24.11.1-rc1 operator
Installed listener=24.11.1-rc1 operator
Installed zookeeper=24.11.1-rc1 operator
Installed hdfs=24.11.1-rc1 operator
Consult the Quickstart to learn more about how to use stackablectl. For example, you can use the --cluster kind flag to create a Kubernetes cluster with kind.

You can also use Helm to install the operators. Add the Stackable Helm repository:

helm repo add stackable-stable https://repo.stackable.tech/repository/helm-stable/

Then install the Stackable Operators:

helm install --wait zookeeper-operator stackable-stable/zookeeper-operator --version 24.11.1-rc1
helm install --wait hdfs-operator stackable-stable/hdfs-operator --version 24.11.1-rc1
helm install --wait commons-operator stackable-stable/commons-operator --version 24.11.1-rc1
helm install --wait secret-operator stackable-stable/secret-operator --version 24.11.1-rc1
helm install --wait listener-operator stackable-stable/listener-operator --version 24.11.1-rc1

Helm deploys the operators in a Kubernetes Deployment and apply the CRDs for the HDFS cluster (as well as the CRDs for the required operators).

What’s next

Set up an HDFS cluster and its dependencies and verify that it works.
