Description

The Execution Engine for Apache Hadoop services integrates the Watson Studio service with your remote Apache Hadoop cluster.

Data scientists can use this service for the following tasks:

  • Browse remote Hadoop data through connections
  • Cleanse and shape remote Hadoop data with Data Refinery
  • Run Data Refinery and jobs on the Hadoop Spark cluster
  • Run a notebook session on the remote Hadoop system
  • Access Hadoop systems with basic utilities from RStudio and Jupyter notebooks

The Execution Engine for Apache Hadoop includes:

  • Services that establish secure connections between Watson Studio and Hadoop
  • Integration with Hadoop for Refinery and Notebook
  • A high availability configuration to the remote Hadoop system
  • Utilities that connect Watson Studio and Hadoop

The service requires a service user who has the necessary privileges to submit requests on behalf of the Watson Studio users to WebHDFS, WebHCAT, Spark, and YARN. The service generates a secure URL for each Watson Studio cluster that is integrated with the Hadoop cluster.
