> I have seen a few instance where I try to click on the job configuration link from the
job history server web ui and it gives a 500 message.  Looking at the job history server log
file it shows an exception like:

> If I go look in hdfs, it doesn't exist in the done_intermediate directory anymore, it
exists in the done directory structure.  hdfs://host.com:9000/home/hadoop/mapred/history/done/2012/02/23/000000/job_1330033607650_0001_conf.xml
> I'm not exactly sure how to reproduce this, but I definitely see it every once in a while.
