[jira] [Created] (HIVE-25241) Simplify Metrics System

David Mollitor created HIVE-25241:
-------------------------------------

             Summary: Simplify Metrics System
                 Key: HIVE-25241
                 URL: https://issues.apache.org/jira/browse/HIVE-25241
             Project: Hive
          Issue Type: Improvement
            Reporter: David Mollitor
            Assignee: David Mollitor


Took a look at the {{Metrics}} stuff in Hive and found a lot of boilerplate code on the client code to interact with Metrics.  It's too much stuff and it's done differently in different places.

* Never allow Metrics System to be "null" - supply a no-op version by default
* Metrics system should never throw an error to the client, just log-and-ignore. Metrics shouldn't break a query or other operation
* General cleanup
