Subject [jira] Updated: (MAPREDUCE-1550) UGI.doAs should not be used for getting the history file of jobs
Date Thu, 09 Sep 2010 11:46:33 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-1550?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Vinod K V updated MAPREDUCE-1550:

        Status: Resolved  (was: Patch Available)
    Resolution: Invalid

Ravi and I sat together to see if it is really valid on trunk. And we reached the conclusion
that it isn't after an elaborate analysis of the order of patches that went into trunk and
yahoo distribution.

>          Components: jobtracker
>    Affects Versions: 0.22.0
>            Reporter: Devaraj Das
>            Assignee: Devaraj Das
>             Fix For: 0.22.0

> When the jobtracker tries to open a job history file it does a doAs to get the filesystem
for the user (that had submitted the job). This should not be done since the job history files
are owned by the jobtracker.
