  - 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 Hue

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

Prerequisites

To set up the EEP repository, see Step 11: Install Ecosystem Components Manually.

NOTE

The Hue package, mapr-hue, can be installed on either a Data Fabric cluster node (recommended) or a Data Fabric client node. If you choose to install on a client node, keep in mind that Hue directories are owned by the user who installed Hue.

About this task

Execute the following commands as root or using sudo.

Procedure

Install the Hue packages.

On Ubuntu:

apt-get install mapr-hue

On RHEL / CentOS:

yum install mapr-hue

On SLES:

zypper install mapr-hue

If the node is a Data Fabric Client node, follow the additional instructions:
1. To determine who the <INSTALL_USER> is, enter:
```
logname
```
2. Set the following properties in hue.ini to that user.
```
server_user=<INSTALL_USER>
server_group=<INSTALL_USER>
default_user=<INSTALL_USER>
```
3. Change the default_hdfs_superuser property to the owner of /var on the cluster.
  
  WARNING
  The <INSTALL_USER> must exist on the cluster on all nodes. It must also be set as the proxy user in all configuration files listed in Configure Hue, depending on the Hue version you are installing.
Run configure.sh -R:
```
/opt/mapr/server/configure.sh -R
```

What to do next

Installing Other Components

Based on your requirements, you may also want to install the following components on at least one node in the cluster.

Component	Description
HPE Ezmeral Data Fabric Database	Required for access to HPE Ezmeral Data Fabric Database tables
HttpFS	Required for viewing files in file system through Hue file browser
Spark	Required to process data using the Notebook UI.
Hive	Required to run queries with HiveServer2.

When you finish installing Hue, go to Configure Hue to learn how to configure Hue.
