Xiao Liang created YARN-8168:

             Summary: Add support in Winutils for reporting CPU cores in all 
CPU groups, and aggregate kernel time, idle time and user time for all CPU 
                 Key: YARN-8168
                 URL: https://issues.apache.org/jira/browse/YARN-8168
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Xiao Liang

Currently winutils can only report the CPU cores of the CPU group that it's 
running in, and the cpuTimeMs calculated from kernel time, idle time and user 
time is also for that CPU group only, which is not complete and incorrect for 
systems with multiple CPU groups (NUMA system for example).
