Subject job.xml and job_jobname_attemptid_conf.xml
Date Sat, 29 Mar 2014 17:14:14 GMT
Hi all,

I submitted a job and it failed. So I checked the intermediate files.
>From the staging/myaccount/.staging directory, I got job.xml. From 
history/done_intermediate/, I got job_jobname_attemptid_conf.xml.
Surprisingly the two files are not exactly the same. Here is the difference
beween  job_jobname_attemptid_conf.xml and job.xml. Anybody knows 
why they are different? Thanks.
