> The totalHitCount and totalMissCount values jump by 2 for each hit/miss operation instead
of jumping by 1.
> Below are the steps:
> - Create a partitioned region with statistics enabled.
> -  run _gfsh>show metrics_ and note the values of _totalHitCount_ and _totalMissCount_
> - Put an entry into the region retrieve it using  _get_ and check the _totalHitCount_.
The value would have doubled.
> - Run a _get_ on a key that is not in the region, and check the _totalMissCount_, it
would have doubled.
