New Features and Changes in Cloudera Data Science Workbench 1.4.3

Major features and updates for Cloudera Data Science Workbench.

Reserve Master Host for Internal Application Components
Cloudera Data Science Workbench now allows you to reserve the master host for running internal application components and services such as Livelog, the PostgreSQL database, and so on, while user workloads run exclusively on worker hosts.

By default, the master host runs both, user workloads as well as the application's internal services. However, depending on the size of your CDSW deployment and the number of workloads running at any given time, it's possible that user workloads might dominate resources on the master host. Enabling this feature will ensure that CDSW's application components always have access to the resources they need on the master host and are not adversely affected by user workloads.

For details on how to enable this feature, see Reserving the Master Host for Internal CDSW Components.

Allow Only Session Creators to Execute Commands in Active Sessions
By default, project contributors, project administrators, and site administrators have the ability to execute commands within your actively running sessions in the Workbench. Cloudera Data Science Workbench 1.4.3 introduces a new feature that allows site administrators to restrict this ability. When this feature is enabled, only the user that creates the session will be able to execute commands in that session. No other users, regardless of their permissions in the team or as project collaborators/administrators, will be able to execute commands on active sessions that were not created by them.

For details on how to enable this feature, see Restricting Collaborator and Administrator Access to Active Sessions.
