      Description

      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
      java.io.FileNotFoundException: File does not exist: /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.
