Analytics Engine HDFS connection

Use the Analytics Engine HDFS connection to connect to IBM Analytics Engine with the WebHDFS API.

IBM Analytics Engine is a Hadoop and Spark service on IBM Cloud that provides an environment to develop and deploy advanced analytics applications. Data is stored in IBM Cloud Object Storage (COS). The Analytics Engine service starts clusters of compute nodes when needed. Analytics Engine HDFS was formerly known as "IBM BigInsights on Cloud."

Create a connection to IBM Analytics Engine

To create the connection asset, you need these connection details:

  • WebHDFS URL: Required.
  • Username. Required.
  • Password
  • SSL certificate if required by the Apache Hive server

Select Use Home As Root to use the username's home directory for the root for browsing.

For Private connectivity, to connect to a database that is not externalized to the internet (for example, behind a firewall), you must set up a secure connection.

Hive properties
The Hive properties are only for when you want to use the Analytics Engine HDFS connection for target (write) data. If you specify Hive properties and you write a file into the target HDFS, then a Hive connection will be established that creates a Hive table for the associated file. If you want to browse the Hive tables of Analytics Engine, use the Apache Hive connection.

  • Hive host: The hostname or IP address of the Apache Hive server.
  • Hive database: The database in Apache Hive.
  • Hive port number: The port number of the Apache Hive server. The default is 10000.
  • Hive HTTP path: The path of the endpoint such as gateway/default/hive when the Apache Hive server is configured for HTTP transport mode.
  • Hive user
  • Hive password

Choose the method for creating a connection based on where you are in the platform

In a project Click New asset > Connection. See Adding a connection to a project.

In a catalog Click Add to catalog > Connection. See Adding a connection asset to a catalog.

In a deployment space Click Add to space > Connection. See Adding data assets to a deployment space.

In the Platform assets catalog Click New connection. See Adding platform connections.

Next step: Add data assets from the connection
