Owen O'Malley commented on HADOOP-2915:
---------------------------------------
I don't see how the added test is testing the relevant code.
The MultipleIOException's toString won't print right. (You need to iterate over
the values, manually...) Furthermore, it should be exceptions.size() + "
exceptions: " + ... instead of "Totally " + exceptions.size() + "exceptions " +
.... Furthermore, you won't see the call stack of the exceptions, which is
pretty critical.
You also missed the job history. It needs to be written as the submitting user
instead of the job tracker.
> mapred output files and directories should be created as the job submitter,
> not tasktracker or jobtracker

> For example, assuming I have installed Hadoop with an account 'hadoop' and I
> am going to run my program with user account 'test'. I have created an input
> folder as /user/test/input/ with user 'test' and the permission is set to
> 0775.
> /user/test/input <dir> 2008-02-27 01:20 rwxr-xr-x test
> hadoop
> When I run the MapReduce code, the output I specified will be set to user
> 'hadoop' instead of 'test'.
> /bin/hadoop jar /tmp/test_perm.jar -m 57 -r 3 "/user/test/input/l"
> "/user/test/output/"
> The directory "/user/test/output/" will have the following permission and
> user:group.
> /user/test/output <dir> 2008-02-27 03:53 rwxr-xr-x hadoop
