need help submit patch to branch-1

[Erik fang]

Hi folks,

I encounter a bug in hadoop 1.0.3 , file a jira and upload a patch in
MAPREDUCE-4451

hope this can be committed to hadoop 1.1.0 or 1.2.0,  so I should commit it
to branch-1?

However, the qa robot runs against trunk , and complains could not apply
the patch

Am I doing something wrong?

Thanks,
Erik
