jobhistory server trying to load job conf file from wrong location
------------------------------------------------------------------
Key: MAPREDUCE-3908
URL: https://issues.apache.org/jira/browse/MAPREDUCE-3908
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mrv1
Affects Versions: 0.23.0
Reporter: Thomas Graves
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:
2012-02-23 22:16:32,519 ERROR org.apache.hadoop.yarn.webapp.View: Error while
reading
hdfs://host.com:9000/home/hadoop/mapred/history/done_intermediate/user/job_1330033607650_0001_conf.xml

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.
