6.2 Installation
This section contains information about installing and upgrading HPE Ezmeral Data Fabric software. It also contains information about how to migrate data and applications from an Apache Hadoop cluster to a HPE Ezmeral Data Fabric cluster.
- 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 data-fabric software and ecosystem components manually.
    - Step 1: Install the Package Key
      Before you install data-fabric packages, you must install the package key.
    - Step 2: Prepare Packages and Repositories
      To install services correctly, each node must have access to the package files.
    - Step 3: Install Cluster Service Packages
      The installation process varies based on the location of your packages and the configuration of your cluster.
    - Step 4: Verify Installation Success
      To confirm success, check each node.
    - Step 5: Set Environment Variables
      Before starting ZooKeeper or Warden, you must complete this step.
    - Step 6: Configure Nodes
      Connect nodes to the cluster, configure security, and arrange node storage.
    - Step 7: 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 8: Install Metrics Monitoring
      Metrics monitoring is part of monitoring, which also includes log monitoring. Monitoring components are available as part of the Ezmeral Ecosystem Pack (EEP) that you selected for the cluster.
    - Step 9: 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 Ezmeral Ecosystem Pack (EEP) that you selected for the cluster.
    - Step 10: Install Ecosystem Components Manually
      You can install one or more ecosystem components from any Ezmeral 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 HPE Ezmeral Data Fabric Streams C Client

The HPE Ezmeral Data Fabric Streams C Client is a distribution of librdkafka that works with HPE Ezmeral Data Fabric Streams.

For instructions on installing the MapR Client, see Installing the Data Fabric Client
For instructions on setting up the EEP repository, see Step 10: Install Ecosystem Components Manually.

Installation

As of MapR 6.0.1, the MapR C client is installed as part of the MapR Core installation and the mapr-client package installation. The MapR C client is available on Linux, Mac, and Windows operating systems.

NOTE Specific installation is not required as of MapR 6.0.1!

For MapR 5.2.1 through MapR 6.0.0, the MapR C client must be installed. The MapR C client is available on Linux and Mac operating systems. As root or using sudo, install the mapr-librdkafka package on nodes where you want to run or build applications.

On Ubuntu:
```
apt-get install mapr-librdkafka
```
On RedHat/CentOS:
```
yum install mapr-librdkafka
```
On SLES:
```
zypper install mapr-librdkafka
```
On Mac OS:
1. Download the following TAR file: https://package.ezmeral.hpe.com/releases/MEP/<MEP version>/<operating system>/<package>.tar.gz
2. Extract the TAR file under /opt/mapr:
```
tar -C /opt/mapr/ -zxf <librdkafka_tarFile_location>
```

NOTE The mapr-librdkafka package pulls in the mapr-client as a dependency if the node does not have the mapr-client or mapr-core package installed.

Configuration

For MapR 6.0.1 and higher, use the following configuration instructions.

Linux

For Linux installations, add /opt/mapr/lib to the end of LD_LIBRARY_PATH.

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/mapr/lib

Mac

For Mac installations, add /opt/mapr/lib to the end of DYLD_LIBRARY_PATH.

export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:/opt/mapr/lib

Windows

For Windows installations, no additional configuration is required. Link your application and run your programs against the HPE Ezmeral Data Fabric Client dynampic link libraries (dll) located at: C:\opt\mapr\lib. The corresponding librdkafka header is C:\opt\mapr\include\librdkafka.

ATTENTION For MapR 6.0.0 and earlier, see Configuring the HPE Ezmeral Data Fabric Streams C Client for instructions on configuring the client.
