Hairong Kuang commented on HADOOP-1298:
---------------------------------------
I ran NNBench on 100 node-cluster. The following shows the transaction rate per
second for operations create/open/delete/rename. The 2nd column is the data of
the current trunk and the 3rd column is the data for trunk+1298 patch. It shows
that trunk+1298 most of the time is faster than the current trunk except for
the open operation. We will rerun the benchmark again tomorrow with a bigger
cluster.

trunk 1298
create 190 201
open 2601 2406
delete 1490 1644

> 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.
