[jira] Created: (HADOOP-2354) Add job-level counters for the launched speculative tasks

Add job-level counters for the launched speculative tasks
---------------------------------------------------------

                 Key: HADOOP-2354
                 URL: https://issues.apache.org/jira/browse/HADOOP-2354
             Project: Hadoop
          Issue Type: Improvement
          Components: mapred
            Reporter: Arun C Murthy
            Assignee: Arun C Murthy
             Fix For: 0.16.0


Add job-level counters for the launched speculative tasks, this should help track them. 

Ideally we would also have counters to check how many of the speculative tasks completed before the original task (thereby helps validate the strategy for launching speculative tasks), however we do not have this infrastructure yet (HADOOP-544) - so I'll file a follow-on bug for that feature.
