1 Overview of Oracle Big Data Manager

Oracle Big Data Manager is a browser-based tool that gives you broad capabilities to manage data across your enterprise. Oracle Big Data Manager is installed and configured by default when you create a cluster.

You can use Oracle Big Data Manager to connect to and interconnect a range of supported Oracle and non-Oracle data storage providers. After you register storage providers, you can preview data and (depending upon the accessibility of each storage provider) compare, copy, and move data between them. With a Hadoop storage provider, you can also move data internally within HDFS. You can also upload data from your local computer to HDFS.

Oracle Big Data Manager provides several methods for data transfer. You can use the console, which includes drag and drop data selection. Python and Java SDKs are available for building data management scripts and applications. There's also a CLI for performing copy operations and for creating and administering data management jobs. 

The Oracle Big Data Manager administrator can create other user accounts and selectively grant access privileges to storage providers.

By default, Oracle Big Data Manager runs on port 8890 on the same node as Cloudera Manager (usually the third node in the cluster).
