Obtaining Data Services deployment files and HDFS support files
To install one or more data VMs to enable ViPR Data Services, you will need to download
the vipr-*-dataservice.zip from the ViPR product page on support.EMC.com.
In addition, if you intend to configure a Hadoop cluster to use ViPR HDFS storage, you will
need to obtain the ViPR HDFS zip file (vipr-hdfs-<version>.zip) from
support.EMC.com. This file contains a JAR file that must be deployed to each client node
in the Hadoop cluster and contains tools to aid the configuration of ViPR to allow access
from the Hadoop cluster.
Before you can set up a Hadoop cluster to use ViPR HDFS, you must complete the
installation and configuration of Data Services. You can then refer to the instructions on
configuring a Hadoop cluster to use ViPR HDFS provided in the
Data Services Solutions
Guide
.
Data Services prerequisite steps
Before you can set up Data Services, make sure that you have prepared the file system
storage that it will use. You also need to have a user account with the required roles to
access the Data Services area of the ViPR UI.
The Data Services area of the UI is designed to guide you through the setup procedure.
Make sure that the following prerequisite steps have been performed to verify that you
have a file virtual pool that can be used by the data service:
u
Create an IP network that contributes file storage to the virtual array (Adding an IP
network on page 54)
u
Create a file virtual pool (Creating or editing a virtual pool for file storage type on page
58 - supporting information is provided in: Virtual pools on page 54)
If you are using EMC Isilon, configure your DNS server to delegate resolution of the Isilon
SmartConnect name to the SmartConnect service. The SmartConnect service returns the
IP address used to connect to the Isilon cluster, based on the load balancing policy that
has been selected.
To access the Data Services area you must have the System Administrator role. Two
additional roles are required to complete the setup: Security Administrator and Tenant
Administrator. The root user account has all of the required roles. Alternatively, the
Security Administrator can assign these roles to a specific user who can perform the
configuration.
The pages in the Data Services area are arranged so that you can work through them from
left to right to complete the installation and configuration.
