Hi,
I'm trying to figure out which log files are used by the job tracker's
web interface to display the following information:
Job Name: my job
Job File:
hdfs://localhost:9000/tmp/hadoop-scohen/mapred/system/job_200809260816_0001/job.xml
Status: Succeeded
Started at: Fri Sep 26 08:18:04 CDT 2008
Finished at: Fri Sep 26 08:18:25 CDT 2008
Finished in: 20sec
What I would like to do is backup the log files that are needed to
display this information so that we can look at it later if the need
arises. When I copy everything from the hadoop home/logs directory into
another hadoop home/logs directory, the jobs show up in the history
page. However, all I see are the job name and starting time, but not the
completion time or the length of the job.
Looks like the JobStatus structure. Perhaps you will need to tune the
logging information to display this when the log finishes, if it is not
listed adequately.
