> Counters that are written to the JobHistory are stringified using {{Counters.makeCompactString()}}.
The format in which this api converts the counter into a string is _groupname.countername:value_.
The problem is that _groupname_ and _countername_ can contain a '.' and hence recovering the
counter becomes difficult. Since JobHistory can be used for various purposes, reconstructing
the counter object back might be useful. One such usecase is HADOOP-3245. There should be
some way to recover the counter object back from its string representation and also to keep
the string version readable.
