Eric Yang resolved HADOOP-4642.
-------------------------------
Resolution: Won't Fix
Job history and job conf data are too big to send through MetricsContext API.
Hence, the better approach is to collect job data through Job History log file
and Job Conf .xml files (HADOOP-4843). Mark this as won't fix.

> Key: HADOOP-4642
> URL: https://issues.apache.org/jira/browse/HADOOP-4642
> Project: Hadoop Core
> Issue Type: New Feature
> Environment: Redhat EL 4.5
> Reporter: Eric Yang
>
> JobConf and JobHistory data contain rich information of the mapreduce job.
> However, the job information are only available temporarily until they are
> expired by JobTracker. This ticket is to request the information to be
> cloned to MetricsContext. This information can be archived by external
> system that interface with Hadoop, such as Chukwa and Ganglia.
