[jira] [Created] (HIVE-10763) LLAP: Provide current attempt start time for wait queue ordering

             Summary: LLAP: Provide current attempt start time for wait queue ordering
                 Key: HIVE-10763
                 URL: https://issues.apache.org/jira/browse/HIVE-10763
             Project: Hive
          Issue Type: Sub-task
    Affects Versions: llap
            Reporter: Prasanth Jayachandran
            Assignee: Siddharth Seth


Wait queue uses first attempt start time for ordering. Since different AMs can submit requests to llap daemon, if AMs are not clocks are not synchronization then this might lead undesired ordering of requests in wait queue. It will be good to have current attempt start time so that the difference between first attempt start time and current attempt start time can be used for ordering.
