             Summary: Investigate IOException usage in Metrics APIs
                 Key: HIVE-14775
             Project: Hive
          Issue Type: Sub-task
            Reporter: Barna Zsombor Klara
            Assignee: Barna Zsombor Klara

A large number of metrics APIs seems to declare to throw IOExceptions 
needlessly. (incrementCounter, decrementCounter etc.)
This is not only misleading but it fills up the code with unnecessary catch 
blocks never to be reached.

We should investigate if these exceptions are thrown at all, and remove them if 
 it is truly unused.
