Subject Swap requirements
Date Wed, 25 Mar 2015 20:45:22 GMT
Hello all,

I am trying to figure out what are the swap requirements for name node and data nodes?  Some
vendor docs that I read says to set vm.swappiness to 0 which is telling kernel to not to use
swap?  

What is the default settings the community is using for there clusters?  

Also does the below parameter uses swap memory or regular memory in yarn?
Yarn.nodemanager.Vmem-pmem-ratio
