Changes in Oracle Big Data Appliance Release 2 (2.1)

The following are changes in Oracle Big Data Appliance Owner's Guide for Oracle Big Data Appliance release 2 (2.1).

Starter Rack and In-Rack Upgrade Kit

Oracle Big Data Appliance is now available as a starter rack with six servers instead of the full rack of 18 servers. An upgrade kit expands the starter rack to 12 servers, and a second upgrade kit expands it to 18 servers.

See "Oracle Big Data Appliance Rack Components" and "Oracle Big Data Appliance Rack Layout."
Multiple Clusters in a Rack

You can now configure a full Oracle Big Data Appliance rack with multiple Hadoop clusters. The smallest cluster size is six servers. Larger clusters must have multiples of three servers.

This support affects the Oracle Big Data Appliance Configuration Worksheets, the network configuration, and the Mammoth software installation.

See Chapter 7.
Cloudera Software Upgrade

Mammoth 2.1.1 installs Cloudera's Distribution including Apache Hadoop (CDH) 4.2.0 and Cloudera Manager 4.5.1.

You can upgrade from Oracle Big Data Appliance 2.0 or 1.1 software.

See "Upgrading the Software on Oracle Big Data Appliance."
Oracle NoSQL Database Enterprise Edition

If you have a license, you can have Mammoth install Oracle NoSQL Database Enterprise Edition instead of the Community Edition.

See "Software Configuration."
The dcli utility uses the Ethernet IP addresses that are stored in the BdaDeploy.json and BdaShip.json files. The rack-hosts-infiniband file is obsolete.

See Chapter 12.

The following are changes in Oracle Big Data Appliance Owner's Guide for Oracle Big Data Appliance release 2 (2.0.1).

Mammoth Upgrade Support

The Mammoth Utility supports upgrades from software version 1.1 to 2.0.1.

See "Upgrading the Software on Oracle Big Data Appliance".
Oracle Enterprise Manager Support

Agents run on Oracle Big Data Appliance to support the Enterprise Manager system monitoring plug-in.

See "Software Configuration."

The following are changes in Oracle Big Data Appliance Owner's Guide for Oracle Big Data Appliance release 2 (2.0).

Oracle Big Data Appliance X3-2

Oracle Big Data Appliance racks are now shipped with a different hardware configuration named Oracle Big Data Appliance X3-2. The Sun Server X3-2L-based racks supersede the Sun Fire X4270 M2-based racks. All versions of the Oracle Big Data Appliance software run on both hardware configurations.

See "Oracle Big Data Appliance Rack Components"
Cloudera's Distribution including Apache Hadoop Version 4 (CDH4)

CDH4 replaces CDH3. CDH4 provides automatic failover of the NameNode and uses different services than CDH3.

See "Port Assignments for Oracle Big Data Appliance Software" for the ports used by CDH4.

See Oracle Big Data Appliance Software User's Guide for more information about using CDH4.
