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.
      - Starting ZooKeeper and Warden
        Starting ZooKeeper and Warden brings up the cluster.
      - Troubleshooting Installation
        If you are having difficulty bringing up the cluster, you have a number of options.
      - Installing the Cluster License
        You must have a valid license to unlock the enterprise features of the HPE Ezmeral Data Fabric. You can obtain a trial license by contacting your HPE support representative.
      - Verifying the Cluster Installation Status
        You can use the command line or the Control System to verify the status of your installation.
    - 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.
    - Step 11: Run configure.sh
      Run configure.sh with the -R option to complete the configuration of ecosystem components that were added manually.
  - Configuring the Cluster
    Describes post-installation configuration tasks for HPE Ezmeral Data Fabric clusters.
- Installing the File Migration Service on the Edge Cluster
  Describes how to install the File Migration service on CentOS nodes.
- Installing the HPE Ezmeral Data Fabric File Store
  Describes how to install File Store software with or without the Installer.
- Installing Kubernetes Interfaces for Data Fabric
  This section describes how to plan for and install the Container Storage Interface (CSI) Storage Plugin and the Kubernetes Interfaces for Data Fabric FlexVolume Driver.
- Upgrading Core or EEP Components
  Depending on your current configuration, you may choose to upgrade the release version (core), ecosystem components, clients, or monitoring components.
- Setting Up Clients and Services
  Describes how to set up and use interfaces to an HPE Ezmeral Data Fabric cluster from a client computer.
- Setting Up the Control System
  Describes how to configure and access the Control System.
- Migrating to the HPE Ezmeral Data Fabric
  Provides instructions for migrating business-critical data and applications from an Apache Hadoop cluster to an HPE Ezmeral Data Fabric cluster.
- Applying a Patch
  You can apply a patch by using the Installer, by using the command line (a manual process), or by using an Installer Stanza.

Verifying the Cluster Installation Status

You can use the command line or the Control System to verify the status of your installation.

Using the CLI to Check the Cluster Installation Status

Log in to a cluster node.

Use the following command to list the HPE Ezmeral Data Fabric services:

maprcli service list
  logpath                                              displayname         name         state
  /opt/mapr/hbase/hbase-1.4.12/logs                    HBaseRestServer     hbaserest    0  
  /opt/mapr/hbase/hbase-1.4.12/logs                    HBaseThriftServer   hbasethrift  0
  /opt/mapr/logs/mfs.log                               FileServer          fileserver   0
  /opt/mapr/grafana/grafana-6.7.4/var/log/grafana      Grafana             grafana      0

  /opt/mapr/opentsdb/opentsdb-2.4.0/var/log/opentsdb   OpenTsdb            opentsdb     0
  /opt/mapr/logs/gateway.log                           GatewayService      gateway      0
  /opt/mapr/logs/hoststats.log                         HostStats           hoststats    0
  /opt/mapr/collectd/collectd-5.10.0/var/log/collectd  CollectD            collectd     0
  /opt/mapr/apiserver/logs/apiserver.log               APIServer           apiserver    0 

maprcli license list
maprcli disk list -host <name or IP address>

Restart Warden on all remaining nodes using the following command:
```
service mapr-warden restart
```
Warden is then responsible for starting the rest of the services configured on each node.

Using the Control System to Check the Cluster Installation Status

Log in to the Control System using the host name of the node where you installed the mapr-webserver. For more information, see Setting Up the Control System.

NOTE Because monitoring has not been installed yet and the Control System relies on monitoring for metrics collection, some Control System functions will not be available. You can still use the Control System to check the cluster services.
Click the Nodes tab to verify that all nodes are present and healthy (no alarms are present).
Click the Services tab to check for any stopped or failed services.
