- Planning the Cluster
  Describes information and factors used in planning your cluster.
- Installing Core and Ecosystem Components
  Describes how to install HPE Ezmeral Data Fabric software and ecosystem components with or without the Installer.
  - 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 with the Installer
    The Installer automates the process of installing Data Fabric software and offers you a variety of options to complete the installation.
  - Installing without the Installer
    Describes how to install HPE Ezmeral 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 Airflow

This topic includes instructions for using package managers to download and install Apache Airflow from the EEP repository.

For instructions to set up the EEP repository, see Step 11: Install Ecosystem Components Manually.

Installation on a Server Node or Edge Node

The Airflow client/server architecture requires you to install three packages on the server node or edge node:

mapr-airflow
mapr-airflow-webserver
mapr-airflow-scheduler

The mapr-airflow-webserver and mapr-airflow-scheduler packages depend on mapr-airflow. The package manager automatically installs mapr-airflow when you install either mapr-airflow-webserver or mapr-airflow-scheduler. Execute the following commands as root or by using sudo on an HPE Ezmeral Data Fabric cluster.

On a node where you want to install Airflow, install mapr-airflow, mapr-airflow-webserver, and mapr-airflow-scheduler:
- On Ubuntu:
```
apt-get install mapr-airflow mapr-airflow-webserver mapr-airflow-scheduler 
```
- On RHEL/CentOS:
```
yum install mapr-airflow mapr-airflow-webserver mapr-airflow-scheduler 
```
- On SLES:
```
zypper install mapr-airflow mapr-airflow-webserver mapr-airflow-scheduler 
```
Note that installations on Oracle Enterprise Linux (OEL) must be done by the root user.
Run configure.sh -R.
```
/opt/mapr/server/configure.sh -R 
```

Installation on a Client Node

Airflow can be installed on a client node. The installation steps are the same as for a server node or edge node. However, after installation on a client node, you must manage all Airflow services manually. For example:

To manage the webserver:

/opt/mapr/airflow/airflow-<version>/bin/airflow.sh [start|stop] webserver

To manage the scheduler:

/opt/mapr/airflow/airflow-<version>/bin/airflow.sh [start|stop] scheduler

Installation on a FIPS Node

Installing Airflow on a FIPS node requires some extra steps:

Install Airflow as described in Installation on a Server Node or Edge Node.
While logged on as the root user, run the repair tool:
```
<airflow_home>/bin/repair_pip_depends.sh
```
Run the configure.sh script:
```
/opt/mapr/server/configure.sh -R
```
Update the Airflow configuration to the FIPS support hash:
```
Change "caching_hash_method = md5" to "caching_hash_method = sha256"
```
Restart Airflow services. See Starting, Stopping, and Restarting Airflow Services.
