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

[David Mollitor (Jira)]

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
