Prerequisites

The following sections describe the hardware and software requirements your environment must meet before you can install BDD.

Supported platforms
At a high level, BDD supports the following platforms.
Supported operating systems
BDD supports the following operating systems:
Hadoop requirements
You must install one of the following Hadoop distributions on your cluster before you install BDD:
Hardware requirements
The hardware requirements for your specific BDD deployment depend on the amount of data you will process. Oracle recommends the following minimum requirements:
Network requirements
Any host machine in a BDD cluster must have a hostname that is externally-resolvable and accessible using the network (IP) address resolved for that hostname. Oracle recommends that host names be fully qualified.
Physical memory and disk space requirements
The physical memory and disk space requirements for each node depend on its type.
Screen resolution requirements
BDD has the following screen resolution requirements:
User access requirements
The Linux user that performs the installation must be the one that will run all BDD processes after the installation and can't be the root user. The following must be configured for this user:
JDK requirements
BDD requires one of the following JDK versions:
Required Linux utilities
The BDD installer requires several Linux utilities.
Database requirements
Studio requires a relational database to store configuration and state, including component configuration, user permissions, and system settings.
Index requirements
The Dgraph requires an index to store the contents of the data sets it can query. It's stored on a shared NFS, which all Dgraph nodes must have read/write access to. Note that at any given time, only one Dgraph instance, the leader, has write access.
Kerberos and Sentry requirements
BDD supports integration with Kerberos 5+ and the version of Sentry included with your Hadoop distribution. If either or both of these are enabled for your Hadoop cluster, you must also enable them for BDD to ensure it can access the data it requires.
Supported Web browsers
Studio support for iPad
You can use the Safari Web browser on an iPad running iOS 7 or later to sign in to Studio and view projects. You cannot use an iPad to create, configure, or export projects.
