Swappiness and Swap Space (Capacity Optimizer only)

A prerequisite for using Pepperdata Capacity Optimizer is for your cluster to be swap-enabled, with sufficient swap space available.

Capacity Optimizer pushes hosts to do more work and to use more physical memory than they otherwise would. To minimize the risk of service outages or application (job) failures due to the Linux Out of Memory (OOM) killer being called if the hosts run out of physical memory, your cluster hosts must adhere to the vendor-recommended settings for swap and swappiness for your Hadoop distribution and operating system. (Although Capacity Optimizer does include a number of safety valves for avoiding this scenario, swap space is required for best results.)

Hadoop Distribution	Recommendation	Vendor Documentation
Cloudera CDH	swapiness = 1 swap space >= 4 GB *	Swappiness setting recommendation

^* Or as recommended by your operating system’s vendor documentation.

You should also consult your operating system’s documentation for recommendations. For example, RedHat recommends swappiness >= 10 (Tuning Virtual Memory ) and that you configure the swap space based on the overall system RAM (Swap Space ).
