I Recent Change History

This appendix describes changes in Releases 4.14 and 4.13. If you are upgrading from an older version of Oracle Big Data Appliance, then it may be informative to read this change summary.

I.1 Changes in Oracle Big Data Appliance Release 4.14

Release 4.14 includes the following new features, software revisions, and other changes.

Release 4.14 is primarily a maintenance release that includes software version upgrades and defect fixes. In addition, there are changes in the distribution of services among the nodes of multirack clusters. Release 4.14 also includes support for Oracle Linux 6 to Oracle Linux 7 migration, which was a post-release add-on to Oracle Big Data Appliance 4.13.

Software Versions in This Release

About Oracle Big Data Discovery

The procedures for installing and upgrading Big Data Discovery on Oracle Big Data Appliance have not changed with release 1.6. This procedure differs from the one described in the Oracle Big Data Discovery Installation Guide.

For upgrades, follow the instructions in the Oracle Big Data Discovery Upgrade Guide

About Perfect Balance

Perfect Balance was removed from Oracle Big Data Appliance as of Release 4.13.

In-Place Procedure for Migrating Big Data Appliance Oracle Linux 6 Clusters to Oracle Linux 7

See Migrating from Oracle Linux 6 to Oracle Linux 7 in this guide.

Uniform Service Layout for Multirack Clusters

In earlier releases, there are difference in the distribution of services among the nodes of a multirack cluster, depending upon whether the cluster was originally configured as multirack or was a single-rack cluster extended to additional racks. In both cases, prior to this release, the services layout in the first rack is different from that of a single rack cluster.

In Oracle Big Data Appliace 4.14, the distribution of services in a single-rack cluster and in the first rack of a multirack cluster are the same. The services on the second and subsequent racks are now consistent regardless of whether the cluster started out as a single-rack or multirack cluster.

Automated Configuration of Replacements for Failed Operating System Disks and Data Disks

The bdaconfiguredisk utility now enables you to configure replacement disks or reconfigure disks with no manual intervention after executing the script. The script supports both OS and data disks.

The Oracle Big Data Appliance Deployment Bundle no Longer Includes the Base Image

The bundle now includes Oracle Big Data Appliance components as RPMs only. The base image is no longer included. There are no changes in the steps you follow to unpack and deploy the bundle.

If you need the base image to bring existing servers up to the minimum release 4.10 base level, see Oracle Big Data Appliance Patch Set Master Note (Doc ID 1485745.1) in My Oracle Support.

I.2 Changes in Oracle Big Data Appliance Release 4.13

Release 4.13 includes the following software revisions and new features.

Note:

This is a post-release update. As of March, 2019 there is now an in-place procedure for migrating Big Data Appliance 4.13 Oracle Linux 6 clusters to Oracle Linux 7. See "Migrating from Oracle Linux 6 to Oracle Linux 7" in this guide.

Software Versions in This Release

Cloudera Enterprise 5.15.1, including CDH, Cloudera Manager, and Key Trustee, Sentry, Impala, Cloudera Search, Apache HBase, Apache Hive, Apache Spark 1.6.

Note that Apache Spark 1.6 is deployed as shipped with CDH, but Mammoth also deploys Apache Spark 2 automatically. The Cloudera parcels for Kudu, Kafka, and Key Trustee Server are included for your convenience, but are not deployed or configured by default.

All servers in existing clusters (not in newly delivered racks) where you are installing Oracle Big Datas Appliance 4.13 must first be updated to at least Oracle Big Data Appliance 4.10.0 before any X7–2L servers can be added as nodes in the cluster.

About Oracle Big Data SQL 3.2.1

Release 3.2.1 is the first Oracle Big Data SQL release to support both Oracle Database 12.2.0.1 and 12.1.0.2. This is the primary feature enhancement in release 3.2.1.

The same Oracle Big Data SQL 3.2.1 installation on a Hadoop cluster can connect to both Oracle Database 12.2.0.1 and 12.1.0.2.

About Oracle Big Data Spatial and Graph 2.5

Release 2.5 includes the following changes:

Count action added to the Spatial Index in the Spark Vector API.
The multimedia analytics feature is deprecated.

About Oracle Big Data Discovery 1.6

Big Data Discovery 1.6 supports Oracle Big Data Appliance 4.13. You can download the installation files from the Oracle Software Delivery Cloud (also known as eDelivery).

The procedures for installing and upgrading Big Data Discovery on Oracle Big Data Appliance have not changed with release 1.6.

For upgrades, follow the instructions in the Oracle Big Data Discovery Upgrade Guide.

About Perfect Balance

Perfect Balance is not included in Oracle Big Data Appliance 4.13. (This software was deprecated in previous releases.)

Disk Shredding for Secure Node Decommissioning

The bdasecureerasenode utility securely erases all data partitions on the node where it is executed. This utility is based on shred command from the GNU Core Utilities.

Users have the option to set the number of shred passes (three is the default). The output of the shred process is logged in /tmp.

Oracle Big Data Manager now Supports External Kerberos Key Distribution Centers

This extends Oracle Big Data Manager compatibility with Kerberos-secured cluster configurations in two ways.

Oracle Big Data Manager now supports AD Kerberos.

In Oracle Big Data Appliance 4.12, Oracle Big Data Manager support for Kerberos-secured clusters was limited to MIT Kerberos.
Oracle Big Data Manager can now run on MIT Kerberos-secured clusters where KDCs are either internal or external to the appliance.

Extensibility and Automatic Upgrade for Kafka Clusters

Kafka clusters are now extensible. This feature was not available in Oracle Big Data Appliance 4.12. The ./mammoth -e command is used to extend both CDH and Kafka clusters. See "Mammoth Options" in thus guide for information about mammoth -e and other options.

Pre-existing Kafka clusters are automatically upgraded to Kafka 3.1.0 during the Mammoth installation.

Note:

The bdacli admin_cluster operations (decommission, recommission, migrate, and reprovision) are not available for Kafka clusters in Oracle Big Data Appliance 4.13.

The Oracle Big Data Appliance Deployment Bundle no Longer Includes the Base Image

The bundle now includes Oracle Big Data Appliance components as RPMs only. The base image is no longer included. There are no changes in the steps you follow to unpack and deploy the bundle.

If you need the base image to bring existing servers up to the minimum release 4.10 base level, see Oracle Big Data Appliance Patch Set Master Note (Doc ID 1485745.1) in My Oracle Support.

SHA-2 Supported for Security Certificates Used with SSL

Oracle Big Data Appliance now supports SHA-2 (specifically, the SHA256, SHA384 and SHA512 Cryptographic Hash Algorithms) for signing SSL certificates.

Active Directory Kerberos on Oracle Big Data Appliance no Longer Requires an SSL Certificate

In this release of Oracle Big Datas Appliance, both the Mammoth installer and the bdacli enable ad_kerberos command enable AD Kerberos without the need of an SSL certificate. AD Kerberos can be enabled whether /opt/oracle/BDAMammoth/active_directory.cer is present or not .

Customers have the option to add an AD Kerberos SSL certificate. Both SHA-1 and SHA-2 are supported.
