After you download the required Hadoop client libraries, you must
configure your installation by updating the
bdd.conf file, which is located in the
/BDD_deployer/installer directory.
Important: bdd.conf defines the
configuration of your BDD cluster and provides the installer with
parameters it requires to run. Updating this file is the most important step of
the installation process. If you don't modify the file, or if you modify it
incorrectly, the installer could fail or your cluster could be
configured differently than you intended.
You can edit the file in any text editor. Be sure to save your changes
before closing.
The installer validates
bdd.conf at runtime and fails if the file contains
any invalid values. To avoid this, keep the following in mind when updating the
file:
- The accepted values for some
properties are case-sensitive and must be entered exactly as they appear in
this document.
- All hostnames must be Fully
Qualified Domain Names (FQDNs).
- Any symlinks in paths must
be identical on all nodes. If any are different or don't exist, the
installation may fail.
- Each port setting must have
a unique value.
- Some of the directories
defined in
bdd.conf have location requirements. These are
specified in this document.
bdd.conf is divided into three parts:
- Required settings: You must
update these properties with information specific to your system and
installation, or the installer may fail.
- Optional settings: You can
update these settings if you want to further customize your installation, but
the defaults will work for most.
- Internal settings: These are
intended for use by Oracle Support, only. Don't edit these unless instructed to
by a support representative.
The required properties are described below. Information about the
optional and internal properties is available in
Optional and Internal BDD Properties.
