Subject [jira] [Created] (YARN-723) Yarn default value of physical cpu cores to virtual core is 2
Date Thu, 23 May 2013 19:01:21 GMT
Bikas Saha created YARN-723:
-------------------------------

             Summary: Yarn default value of physical cpu cores to virtual core is 2
                 Key: YARN-723
                 URL: https://issues.apache.org/jira/browse/YARN-723
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Bikas Saha


The default virtual core allocation in the RM is 1. That means every container will get 1
virtual core == 1/2 a physical core. Not sure if this breaks implicit MR assumptions of maps/reduces
getting at least 1 physical cpu.
