Installing the Data Fabric Client

This section describes how to prepare your machine for the installation process.

About this task

CAUTION: Do not attempt to install Ecosystem Pack (MEP) service components on client nodes. Client nodes do not have the service-management framework required to host the service components.
Before you install the data-fabric client, perform the following steps:

Procedure

  • Verify that the operating system on the machine where you plan to install the client is supported. For a list of operating systems that are compatible with the data-fabric clients, see Client Support Matrix.
  • Verify that the machine where you plan to install the client is not a cluster node. The data-fabric client is intended for use on a computer that has no other data-fabric server software installed.
  • Ensure that the hostname of the system is set to a fully qualified DNS name. This is critical as else configure.sh will fail to generate SSL keys.
  • Obtain connectivity information and cluster setup requirements. When you use configure.sh to configure the client, you will need to know the following details:
    • The cluster name. You will need the cluster name when you specify the -N parameter.
    • The IP addresses and ports of the CLDB nodes on the cluster. You will need this information when you specify the CLDB nodes with the -C parameter.
    • If one or more nodes in the cluster run the ResourceManager, you may need to specify the hostname or IP address for each ResourceManager nodes using the -RM parameter. If the cluster is configured to use zero-configuration failover, do not specify the ResourceManager nodes. If the cluster is not configured to use zero-configuration failover, specify each ResourceManager node.
    • Determine if the cluster is secure. If the cluster is secure, you will need to specify the -secure parameter when you run configure.sh.
    • If a node in the cluster runs the HistoryServer, note the hostname for the HistoryServer. You must specify each HistoryServer node using the -HS parameter.
  • In the /etc/hosts file of the client machine, add a mapping between the CLDB nodes in the cluster and the IP addresses of those nodes.
    For example, add the IP address 10.10.82.22 and CLDB node name centos22 on the Mac OSX where you installed the client:
    127.0.0.1       localhost
    255.255.255.255 broadcasthost
    ::1             localhost
    fe80::1%lo0     localhost
    10.10.82.22     centos22

What to do next

To install the client, obtain the data-fabric packages for your operating system at https://package.mapr.hpe.com/releases/ and complete the installation steps:

For the Windows client, see: Installing the Data Fabric Client on Windows.

Warning: The client nodes also need to have the data-fabric repositories configured in order to pull the client packages. See Data Fabric Repositories and Packages.
