[jira] [Created] (YARN-7159) Normalize unit of resource objects in RM and avoid to do unit conversion in critical path

Wangda Tan created YARN-7159:
--------------------------------

             Summary: Normalize unit of resource objects in RM and avoid to do unit conversion in critical path
                 Key: YARN-7159
                 URL: https://issues.apache.org/jira/browse/YARN-7159
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Wangda Tan
            Assignee: Wangda Tan
            Priority: Critical


Currently resource conversion could happen in critical code path when different unit is specified by client. This could impact performance and throughput of RM a lot. We should do unit normalization when resource passed to RM and avoid expensive unit conversion every time.
