Can I Delete Components Installed in an MRS Cluster?

Question:

Can I delete components from an existing MRS cluster?

Answer:

You cannot delete any component from a cluster in MRS 3.1.0 and earlier versions. If a component is not required, log in to MRS Manager and stop the component on the Services page.

You can add components to MRS 3.1.2-LTS.3 or later custom clusters. For details, see Managing Services.
