Cloudera application is highly sensitive to system swapping. What are the recommended approaches to reduce system swap activity?

Issue

• Even a low rate of system swapping negatively impacts the Cloudera application, which is highly sensitive to swap activity.
• The system is just producing a small swapping (6GB of 100GB) but it still poses an issue in the application.
• Despite a large amount of available memory, the OS appears to be actively swapping out anonymous pages.
