New and Enhanced Features
Oracle Shell for Hadoop Loaders
Oracle Shell for Hadoop Loaders is a new user interface for Big Data Connectors. Is it not itself a Big Data Connector. Oracle Shell for Hadoop Loaders is a shell and command line that provides the user with a single environment for interacting with Big Data Connectors – Oracle Loader for Hadoop, Oracle SQL Connector for HDFS, and Copy to Hadoop. In addition to providing a single point of access, Oracle Shell for Hadoop Loaders can reduce some of the overhead involved in using the Connectors, because otherwise these products must be configured, managed, and run separately.
Oracle R Advanced Analytics for Hadoop (ORAAH) 2.6 Improvements
ORAAH 2.6 includes expanded support for predictive modeling algorithms, including integration of many Spark MLlib capabilities, as well as enhancements for existing custom Spark algorithms.
Oracle XQuery for Hadoop 4.5.0 Improvements
Adds support for W3C XQuery 3.0 including the try/catch expression, the switch expression, and standard functions and operators.
