  It is essential that patches for JIRA issues are generated with the {{{--=
no-prefix}}} option. Without that an extra directory path is listed, and th=
e patches can only be applied with a {{{patch -p1}}} call, ''which Hudson d=
oes not know to do''. If you want your patches to take, this is what you ha=
ve to do. You can of course test this yourself by using a command like {{{p=
atch -p0 << ../outgoing/HDFS-775.1}}} in a copy of the SVN source tree to t=
est that your patch takes.
  =

+ If you have checked in your patch, then you need to refer to the patch by=
 name (SHA1 checksum, and that of the preceeding patch. If it was the last =
patch and nothing else changed, this is easy.
+ {{{
+ git diff --no-prefix HEAD~1 HEAD
