[jira] [Created] (IMPALA-12325) Query log with query level metrics

Quanlong Huang created IMPALA-12325:
---------------------------------------

             Summary: Query log with query level metrics
                 Key: IMPALA-12325
                 URL: https://issues.apache.org/jira/browse/IMPALA-12325
             Project: IMPALA
          Issue Type: New Feature
          Components: Backend
            Reporter: Quanlong Huang


Coordinators will dump query profiles to local disk in the log folder (configured by startup flag --profile_log_dir). However, it's inconvenient to parse the profiles for metric collector tools. It'd be useful if coordinators also dump a query log with query id, query string and some query level metrics, including all we show in the /queries WebUI, and some more useful metrics in the profile, e.g.
 * number of hosts
 * number of fragment instances
 * ClientFetchWaitTimer
 * Total/Avg of NetworkReceiveTime
 * Total/Avg of NetworkSendTime
