[jira] [Created] (YARN-8168) Add support in Winutils for reporting
CPU cores in all CPU groups, and aggregate kernel time, idle time and user
time for all CPU groups
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 groups
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).
