Cloudera Manager, Hue, and the Spark History Server
Cloudera Data Science Workbench also gives you a way to access your CDH cluster's Cloudera Manager and Hue UIs from within the Cloudera Data Science Workbench application. Spark 2 provides a UI that displays information and logs for completed Spark applications, which is useful for debugging and performance monitoring.
This UI, called the History Server, runs on the CDH cluster, on a configurable host and port.
To access these applications, click the grid icon in the upper right hand corner of the Cloudera Data Science Workbench web application, and select the UI you want to visit from the dropdown.
