Installation and Upgrade Overview
The Big Data Management installer includes components that allow communication between the Informatica domain and the Hadoop environment. You can install Big Data Management in a single node environment or in a cluster environment.
If you upgraded the Informatica platform or applied the hotfix, you need to uninstall Big Data Management from the cluster and perform a new installation. You also perform the installation configuration tasks in addition to some upgrade tasks.
To install or upgrade Big Data Management, complete the following high-level tasks:
- 1. Complete prerequisite tasks. Prerequisite tasks include verifying minimum system requirements, creating users and directories, and installing third-party products. If you upgraded the Informatica platform or applied the hotfix, you must also uninstall Big Data Management from the cluster.
- 2. Run the installer. Download a package associated with the Hadoop distribution, and run the installer in the Hadoop environment.
- 3. Configure the environments. Run the Informatica Hadoop Configuration Manager (the configuration manager) on the machine that hosts the Data Integration Service to establish communication between the Informatica and Hadoop environments. After you run the configuration manager, you perform configuration tasks in both the domain and the Hadoop environments. If you upgraded the Informatica platform or applied the hotfix, you need to perform additional configuration tasks.
