Overview of the new Oracle JDK version and support of HBase with JavaDB
Oracle provides two supported Java Development Kit (JDK) editions, Oracle Java SE 6, and Oracle Java SE 7. The Oracle Java SE 6 JDK is certified as a Windows-based client browser and Android-based client browser for Oracle E-Business Suite 12.1.3.1 and lower. The Oracle Java SE 7 JDK is certified as a Windows-based client browser and Android-based client browser for Oracle E-Business Suite 12.2 and lower.
It is possible to run the same HBase application as with earlier versions of JavaDB in an environment that supports Java SE 7. The deployment environment and connectivity to HBase must be consistent with those described in previous releases. Changes in the behavior of some databases in this release may affect the behavior of the HBase application. For example, in some databases, for a call to the GetSchema() method on a row or column, the schema will be set to the schema specified by the database, rather than the schema assigned in the HBase configuration.
Overview of the new Oracle JDK version and support of HBase with HBase-JDBC
The JDBC 3.0 specification is a new product, available in April 2011. The HBase-JDBC module includes the following updated components:
HBaseLib: This module includes the HBase specific functions, such as GetValue(), PutValue(), DeleteValue(), AlterColumnFamily(), and CreateTableIfNotExist(), as well as additional functions to integrate with JDBC 3.0.
HBaseJava: This module contains new package names, namespaces, and signature of the HBase methods and tables.
The older Oracle JDK versions do not contain all the features provided by the JDBC 3.0 specification. To support the Java SE 7 and JDK 7, you must install the JDK update J7 on your client platform and follow the Java SE 7 instructions to make the necessary changes to your Java installation.
This article explains how to use the JDBC 3.0 features in HBase-JDBC.
Make sure that the Java SE 7 version is installed. For more information, see the Oracle Java SE 7 Platform Update 4 (JSR 003) website.
If you are not already using a JDBC driver, download and install the Oracle JDBC Driver for your platform. For more information,
