mapreduce.CounterGroup constructor should not be public
-------------------------------------------------------
Key: MAPREDUCE-2335
URL: https://issues.apache.org/jira/browse/MAPREDUCE-2335
Project: Hadoop Map/Reduce
Issue Type: Bug
Reporter: Luke Lu
MAPREDUCE-980 (made into 0.21+) changed the constructor from package protected
to public. As we all know: nothing good happens after making a constructor
public, especially for public facing APIs. There is no other use of the
constructor outside the EventReader yet. To avoid another API change debacle in
case of external user usage and later we decide to refactor counters for more
efficient internal implementations (e.g. a la MAPREDUCE-901), we should make
the Counter/CounterGroup constructors package private, and provide a method to
addGroup to Counters. Or at least make the constructor
@InterfaceAudience.Private.
