             Summary: Retrieve app taskGroups from pod spec
                 Key: YUNIKORN-458
                 URL: https://issues.apache.org/jira/browse/YUNIKORN-458
             Project: Apache YuniKorn
          Issue Type: Sub-task
          Components: shim - kubernetes
            Reporter: Weiwei Yang


YUNIKORN-439 has added the utility function to retrieve taskGroups from pod annotation.
This task needs to leverage that function to get taskGroups while creating {{pkg/cache/application}} object. For normal apps, we directly retrieve the taskGroups info from the *first pod* seen by the scheduler.

There are a few assumptions
# If there are multiple pods in one app. The 1st pod must have the taskGroups defined, or all the pods should have same taskGroups definition.
# If there are multiple taskGroups defined, different pods that belong to different groups need to set “yunikorn.apache.org/taskGroupName” accordingly.
