Christophe Taton updated HADOOP-1298:
-------------------------------------
Attachment: fsdirectory-cleanup-20070725-1351.patch
Hi all,
In trying to reduce the insane previous patch, would you allow me this small
code cleanup patch?
It mainly changes FSDirectory:
- lets FSDirectory.INode become a static class, which spares one pointer per
INode
- removes an unused constructor for FSDirectory.INode
- merges identical methods INode.getAbsoluteName() and INode.computeName() and
optimize it using StringBuffer
- introduces EMPTY_BLOCKS_ARRAY instead of having block==null and
EMPTY_CHILDREN_MAP to use for INode without children instead of having
children==null (code readability).
The patch is 280 lines long. All JUnit tests pass.
Thanks,
Christophe T.

> I'm working on adding a permissions model to hadoop's DFS. The first step is
> this change, which associates user info with files. Following this I'll
> assoicate permissions info, then block methods based on that user info, then
> authorization of the user info.
> So, right now i've implemented adding user info to files. I'm looking for
> feedback before I clean this up and make it offical.
> I wasn't sure what release, i'm working off trunk.
