- 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.

Installing Additional Core Features

Some features can require additional configuration or the installation of additional packages after an upgrade to a new release.

Installing the HPE Ezmeral Data Fabric Object Store After an Upgrade

Use these steps:

Install the mapr-s3server package on all cluster nodes. For more information about installing cluster service packages, see Step 4: Install Cluster Service Packages.

Enable Object Store support if it is not already enabled:

maprcli cluster feature enable -name cldb.objectstore.support -force true -json

Restart the CLDB services on the CLDB secondary nodes:
```
/opt/mapr/bin/maprcli node services -cldb restart -nodes node1 node2 node3
```
For more information about node services, see node services.
Generate the Object Store certificates by using the manageSSLKeys.sh:
- After upgrading from core 6.2.0 to 7.0.0 or later:
```
manageSSLKeys.sh createusercert -a moss -u *.<domain_name> -ug <cluster_admin_id>:<cluster_admin_group>
```
  In this command, -u specifies the domain name.
- After upgrading from core 6.1.x to 7.0.0 or later:
```
manageSSLKeys.sh createusercerts -ug <cluster_admin_id>:<cluster_admin_group> -N <cluster_name>
```
Complete all steps in Enabling the HPE Ezmeral Data Fabric Object Store.

Installing Airflow After an Upgrade

Airflow is a new ecosystem component. After an upgrade to release 7.0.0, you must install Airflow manually. See Step 11: Install Ecosystem Components Manually.

Installing Monitoring After an Upgrade

Monitoring, also known as the Spyglass initiative, provides the ability to collect, store, and view metrics and logs for nodes, services, and jobs/applications. You can only install Monitoring after you upgrade ecosystem components.

To install Monitoring without the Installer, see Step 9: Install Metrics Monitoring and Step 10: Install Log Monitoring.
