Alejandro Abdelnur commented on MAPREDUCE-3868:
-----------------------------------------------

most of the patch is just moving files around, doing that with 'patch' will 
delete/create those files and subversion will not know bind them. This means 
that all changes prior this this JIRA will be lost as all the moved files will 
be (from SVN perspective) new files. you won't be able to track previous 
changes directly. The original patch I've submitted as a script/combo patch, 
the script does 'svn mv' which tells SVN to bind the files in the new location 
with the old location thus allowing you to trace changes to the first commit of 
the files. the script works both in filesystem and SVN mode.
