Vinod K V commented on MAPREDUCE-829:
-------------------------------------
This is not a problem in usual scenarios when TaskTracker process space creates
JobConf objects and automatically loads mapred-default.xml and mapred-site.xml
in it's classpath via JobConf's static block. But this is still a problem when
these files are not used and instead TT is setup via a passed JobConf object,
for e.g. in a test environment.
> When localizing job configuration from FS, TTs configuration on local disk is
> not loaded at all

> We should first load the local configuration fConf, over which the job.xml
> from the JobTracker's file system should be loaded. This is needed so as to
> enforce settings specific to the TaskTracker if it has some.
