Barna Zsombor Klara updated HIVE-14775:
---------------------------------------
    Description: 
A large number of metrics APIs seem 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.
