CDSW on top or beside CDH?

[#1]

I have a 4 node CDH cluster and want to add CDSW. Does adding CDSW entail adding a new host onto the cluster or is CDSW ran on top of the CDH cluster?

@TheBroMeister  Yes, you require the new set of hosts to install CDSW on that. Cloudera Data Science Workbench does not support running any other services except gateway roles on CDSW dedicated hosts. 

Cloudera Data Science Workbench runs on one or more dedicated gateway hosts on CDH clusters. Each of these hosts has the Cloudera Manager Agent installed on them. 

Each gateway host must be dedicated solely to Cloudera Data Science Workbench. This is because user workloads require dedicated CPU and memory, which might conflict with other services running on these hosts. You can refer the CDSW architecture from below doc.
