Reserving the Master Host for Internal CDSW Components

Cloudera Data Science Workbench 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.

Depending on your deployment type, use one of the following sets of instructions to enable this feature:

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.
