Subject Regarding Yarn virtual core configuration.
Date Sat, 10 Dec 2016 06:24:18 GMT
Hi all,
                 I have a doubt in setting the Yarn's virtual core
configuration. I have an Intel CPU slaves with hyperthreading enabled. The
total number of physical core is 8. Logical core is twice the physical core
( 8 * 2 = 16 ). While setting the "yarn.nodemanager.resource.cpu-vcores"
property, which value should I give ( 8 or 16 ) ?. I am trying to maximize
the virtual core usage so that the job can be finished faster. Looking
forward to hear from you

Regards,
Sairam Kannan
