Xiaochang Wu created SPARK-36173:
------------------------------------

             Summary: [CORE] Support getting CPU number in TaskContext
                 Key: SPARK-36173
                 URL: https://issues.apache.org/jira/browse/SPARK-36173
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 3.1.2
            Reporter: Xiaochang Wu


In stage-level resource scheduling, the allocated 3rd party resources can be obtained in TaskContext using resources() interface, however there is no API to get how many cpus are allocated for the task. Will add a cpus() interface to TaskContext in addition to resources().
