Subject [jira] [Created] (YARN-9782) Avoid DNS resolution while running SLS.
Date Sun, 25 Aug 2019 07:00:05 GMT
Abhishek Modi created YARN-9782:
-----------------------------------

             Summary: Avoid DNS resolution while running SLS.
                 Key: YARN-9782
                 URL: https://issues.apache.org/jira/browse/YARN-9782
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Abhishek Modi
            Assignee: Abhishek Modi


In SLS, we add nodes with random names and rack. DNS resolution of these nodes takes around
2 seconds because it will timeout after that. This makes the result of SLS unreliable and
adds spikes.
