How Do You Prevent Tasks From Running On Hybris Commerce Front-End Storefront Nodes?

Answer

1. Go to your local.properties file in the hybris/bin folder.
2.  Enter the following: task.excluded.cluster.ids=1,2
   This entry will prevent nodes 1 and 2 (front-end nodes in my case) from processing tasks.

Additional Background

With OOTB Hybris Commerce, all nodes are eligible to process tasks from the task queue. In production, front-end storefront nodes should be configured to process customer traffic only, and not used to process backoffice tasks, which tend to require a significant amount of system resources at times.
