G.6 Changes in Oracle Big Data Appliance Release 4 (4.5)

The following are changes in Oracle Big Data Appliance Release 4 (4.5):

Software Updates

  • CDH (Cloudera's Distribution including Apache Hadoop) 5.7

  • CDM (Cloudera Manager) 5.7

  • Cloudera Navigator 2.4.1

  • Java JDK 8u92

  • Oracle Big Data Connectors 4.5

  • Oracle Data Integrator Agent 12.2.1 (for Oracle Big Data Connectors)

  • Oracle NoSQL Database 4.0.5

  • Perfect Balance 2.7

  • Big Data Discovery 1.2.2 (optional)

  • Big Data SQL 3.0.1 (optional)

Hardware Updates

  • Oracle Big Data Appliance X6-2 server

    The X6-2 provides substantial increases in processing power and memory over X5–2 servers:

    • 2 x 22-core (2.2GHz) Intel® Xeon® E5-2699 v4 processors.

    • 8 x 32 GB DDR4-2400 memory (expandable to maximum of 768 GB per node).

    X6-2 servers are shipped with an Oracle Big Data Appliance v4.4.0 base image.

    X6-2 nodes can be mixed with X5-2 nodes (and older Release 4.5–compatible nodes) in a CDH or NoSQL cluster. The X6-2 server is not compatible as a node of an Oracle Big Data Appliance cluster in releases prior to Oracle Big Data Appliance Release 4.4.

    See the Oracle Big Data Appliance X6-2 Data Sheet for more details.

New Features

  • Cloudera CDH 5.7 and Cloudera Manager 5.7

    See the Cloudera Enterprise 5.7.x Documentation for information about CDH 5.7 and Cloudera Manager 5.7

    Upgrades to CDH 5.7.1 are supported. Note that this upgrade is required in order to install Oracle Big Data Discovery 1.2.2 on Oracle Big Data Appliance 4.5.

  • Support for Either Local or Remote Key Trustee Servers

    Oracle Big Data Appliance supports both local and remote Key Trustee Servers for HDFS Transparent Encryption. The Oracle Big Data Configuration Utility includes HDFS Transparent Encryption as a configuration option. You can either click a checkbox to automatically install and configure active and passive Key Trustee Servers locally on the Oracle Big Data Appliance or define an “off-board” configuration, including the address of the active and passive servers, the Key Trustee organization, and the authorization code. You can also enable HDFS Transparent Encryption via the bdacli utility at any time after Mammoth installation and will be prompted to make the same choice between remote or local key trustee services.

    Athough Oracle Big Data Appliance supports local Key Trustee Servers, remote servers are still the recommended choice.

  • Support for Oracle Big Data SQL 3.0.1

    Oracle Big Data Appliance Release 4.5 includes Oracle Big Data SQL 3.0.1 as a Mammoth installation option. See the Oracle Big Data SQL User's Guide for Release 3.0.1 installation instructions.

  • Enhanced Networking

    Release 4.5 provides more flexibility in the configuration of networks on the Oracle Big Data Appliance. This includes support for the following options:

    • Separate networks for each cluster in a rack (both client and private networks).

    • Multiple client networks on the same BDA cluster.

    • VLAN tagging for client networks.

    • Partition keys for private InfiniBand networks.

  • Lower Minimum Size for CDH Clusters

    The minimum recommended CDH cluster size for a production environment is now five nodes. For development purposes, the Oracle Big Data Appliance Configuration Generation Utility now enables you to create three-node CDH clusters.

    Note that Oracle Big Data Appliance Starter Rack is still sold with six servers.
