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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
