Amareshwari Sriramadasu commented on HADOOP-3970:
-------------------------------------------------
bq. I think the escapeString(String str, char escapeChar, char charToEscape)
API is still useful by itself, and is easier to use in cases where the user has
only one char to escape.
+1 I agree with Hemant to not deprecate the api escapeString(String str, char
escapeChar, char charToEscape).
> Counters written to the job history cannot be recovered back

> 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.
