Subject One query related to cgroupsin 2.4.1
Date Fri, 07 Nov 2014 10:37:33 GMT
Hi All,

In 2.4.1 When there is multiple components like Hbase and yarn runnning on the same node can
we restrict the cpu usage of of all YARN containers in that NM through cgroups
Assume a node has 10 cores and cpu vcores for this NM is configured to 7. so suppose 7 containers
each requesting for 1 core is run does cgroup ensure that cpu usgae of all the containers
do not increase more than 700% by all the containers?

Basically I want to restrict the cpu usage of all the containers in a given node so that the
system processes and other components like HDFS, hbase etc.. run well along with YARN
How to acheive this?
