     [ https://issues.apache.org/jira/browse/HADOOP-5737?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Vinod K V updated HADOOP-5737:
------------------------------

    Release Note: Fixed JobTracker to use it's own credentials instead of the job's credentials for accessing mapred.system.dir. Also added APIs in the JobTracker to get the FileSystem objects as per the JobTracker's configuration.  (was: Fixed a problem in the way the JobTracker used to talk to other daemons like the NameNode to get the job's files. Also added APIs in the JobTracker to get the FileSystem objects as per the JobTracker's configuration.)

> While initializing a job, the ugi information should point to jobtracker as jobtracker does a dfs read. But today we will see that the log shows _pi_ as the caller instead of the jobtracker.
