- Planning the Cluster
  Describes information and factors used in planning your cluster.
- Installation Methods
  Describes different ways to install the HPE Data Fabric.
  - Installing with a Seed Node
    Describes how to install the platform using a seed node and the Create Fabric interface.
  - Installing Manually
    Describes how to install HPE Data Fabric software and ecosystem components by using the command line.
    - Data Fabric Repositories and Packages
      Describes the repositories for Data Fabric software and the ecosystem components.
    - Package Dependencies
      Lists the interdependencies between packages across all the supported Operating Systems
    - Preparing Each Node
      Defines minimum requirements for each node in your cluster.
    - Installing without the Installer
      Describes how to install HPE Data Fabric software and ecosystem components manually.
      - Step 1: (Optional) Enable FIPS Mode
        If your cluster must be FIPS-compliant, you must enable FIPS mode at the operating system level before installing Data Fabric software. If FIPS compliance is not needed, you can skip this step.
      - Step 2: Import the Package Key
        Before you install Data Fabric packages, you must import the package key.
      - Step 3: Prepare Packages and Repositories
        To install services correctly, each node must have access to the package files.
      - Step 4: Install Cluster Service Packages
        The installation process varies based on the location of your packages and the configuration of your cluster.
      - Step 5: Verify Installation Success
        To confirm success, check each node.
      - Step 6: Set Environment Variables
        Before starting ZooKeeper or Warden, you must complete this step.
      - Step 7: Configure Nodes
        Connect nodes to the cluster, configure security, and arrange node storage.
      - Step 8: Bring up the Cluster
        Before you can install monitoring or ecosystem components, you must enable the cluster by starting ZooKeeper and Warden and verifying the cluster installation status.
      - Step 9: Install Metrics Monitoring
        Metrics monitoring is part of monitoring, which also includes log monitoring. Monitoring components are available as part of the Ecosystem Pack (EEP) that you selected for the cluster.
      - Step 10: Install Log Monitoring
        Installing the monitoring logging components is optional. The logging components enable the collection, storage, and visualization of core logs, system logs, and ecosystem component logs. Monitoring components are available as part of the Ecosystem Pack (EEP) that you selected for the cluster.
      - Step 11: Install Ecosystem Components Manually
        You can install one or more ecosystem components from any Ecosystem Pack (EEP) that is supported by the Data Fabric cluster version. An EEP consists of a group of ecosystem components that work together.

Installing Flink

This topic includes instructions for using package managers to download and install, or remove Flink from the DEP.

Before Installing Flink

Consider the following points before you install the mapr-flink package:

You must install the mapr-flink package on a cluster node that runs Flink CLI tools.
You can install mapr-flink package on a single node. YARN installs the Flink on other nodes of the cluster that has node manager running.
NOTE
To run Flink as a YARN application, you must install mapr-flink package on a host that has mapr-hadoop-client installed.
.

Install Flink

On the node you want to install Flink, run the following commands as root user or with sudo:

Ubuntu: apt install mapr-flink
RHEL: yum install mapr-flink

Remove Flink

Flink does not stop any running jobs or clusters upon package removal. To stop any running Flink processes before package removal, do the steps that follow:

If you want to save any running job's state and use it in future, stop the job and create a savepoint, run:
```
/opt/mapr/flink/flink-<version>/bin/flink stop <job_id> --savepointPath <savepoints_directory>
```
Save the given in the output savepoint path (you may want to use after reinstallation).
OR
If you want to cancel the job without saving the job's state, run:
```
/opt/mapr/flink/flink-<version>/bin/flink cancel <job_id>
```

To stop any running Flink cluster (YARN application), run:

echo "stop" | /opt/mapr/flink/flink-<version>/bin/yarn-session.sh -id <application_id>

Post Installation Steps

To configure Flink, see Configuring Flink.
