For Parsing job history logs in H23, One way I see is to figure out the history file path (JobHistoryUtils.getConfiguredHistoryServerDoneDirPrefix(conf)/YYYY/MM/DD/<job serial number>/<job_id>-*.jhist) . Then parse it with JobHistoryParser to get a JobInfo object out of it.
There's also a JobHistory server now, but I don't see code which would return me jobhistory file location or some parseable content (json?) for constructing the Jobinfo obj. I was just curious that whether the first approach is OK, or are there more better ways to achieve this?
