Amareshwari Sri Ramadasu commented on HADOOP-2178:
--------------------------------------------------
bq.In the case of HOD deployed JTs, I think we can then either set
hadoop.job.history.location to NULL or to a HOD specified output directory,
probably on HDFS or another shared FS. This would be useful if the user is
running a lot jobs through a single HOD instance. NULL is probably a fine
default.
In case of HOD, hadoop.job.history.location default value can be local file
system, sothat HOD can collect logs at the shutdown of cluster as is today.

> This issue addresses the following items :
> 1. Check for accuracy of job tracker history logs.
> 2. After completion of the job, copy the JobHistory.log(Master index file)
> and the job history files to the DFS.
> 3. User can load the history with commands

> or
> bin/hadoop job -history <jobid>
> This will start a stand-alone jetty and load jsps
