Hi Amit,

The job history files are stored in HDFS. eg. /mapred/history/done/2013/02/06/000000

I would think that there would be some changes in the format.

Subject: Job History files in Hadoop 2.0

I recently migrated to Hadoop 2.0 from Hadoop 1.0 (0.20.2 before).

I am able to successfully launch example applications.

/Could anyone please suggest where are the MapReduce job history files
available, after running jobs in Hadoop 2.0./

I need the statistics after running the jobs. Of course, the web UI gives me
the information. But I need the history files that were available in the
previous versions of hadoop job_ID etc.

I can see a directory with application and container patterns but this does
not have specific information about job submit time, Map Start time, finish
time, reduce start time, finish time, job finish time etc. 

In the previous version of hadoop i.e. 1.0 or 0.20, it was stored under

Can anyone suggest if the pattern of storing job history files is also
changed in the new architecture?

Thanks in advance,
