[jira] [Created] (YUNIKORN-85) Improve recovery performance by querying all pods once instead of querying pods on specified node for many times

Tao Yang created YUNIKORN-85:
--------------------------------

             Summary: Improve recovery performance by querying all pods once instead of querying pods on specified node for many times
                 Key: YUNIKORN-85
                 URL: https://issues.apache.org/jira/browse/YUNIKORN-85
             Project: Apache YuniKorn
          Issue Type: Improvement
          Components: shim - kubernetes
            Reporter: Tao Yang


Recently I did some performance tests on kubemark cluster with 1k hollow nodes, and found the recovery phase will take almost 1 minute, querying pods on specified node one by one is the most time-consuming logic inside. Therefore I propose to query all pods once here to improve the recovery performance, after this improvement, the cost time of recovery phase can reduce to only 2 seconds.
