Before You Install CDH4 on a Single Node
Before you install CDH4 on a single node, there are some important steps you need to do to prepare your system:
- Verify you are using a supported operating system for CDH4. See CDH4 Requirements and Supported Versions.
- If you haven't already done so, install the Oracle Java Development Kit (JDK) before deploying CDH4. See the section: Install the Oracle Java Development Kit.
On SLES 11 platforms, do not install or try to use the IBM Java version bundled with the SLES distribution; Hadoop will not run correctly with that version. Install the Oracle JDK following directions under Install the Oracle Java Development Kit..
