Subject [jira] [Resolved] (MAPREDUCE-4080) FileNotFoundException while accessing job configuration from UI.
Date Thu, 29 Mar 2012 14:30:27 GMT

Robert Joseph Evans resolved MAPREDUCE-4080.
--------------------------------------------

    Resolution: Duplicate

I saw this same issue while working on MAPREDUCE-3972, and I fixed it as part of that JIRA.
 I did this because I considered it a threading issue.  The move from done_intermediate to
done was not coordinated with the reading of the Configuration file. It also was not coordinated
with reading the jhist file or many other things.

> Tried to access the job configuration from UI, when the job history files were still
in the intermediate directory. JHS displayed the configurations of the job. Again tried to
access the configurations of the same job, when the job history files were in the done directory.
This time got the following exception
> {noformat}
> java.io.FileNotFoundException: File does not exist: /jobhistory/intermediate/kamesh/job_1332999698561_0005_conf.xml
