I agree with Amar and James,
if you require permissions for your project,
then
1. create a group in linux for your user.
2. give group write access to all files in HDFS. (hadoop dfs -chmod -R
g+w / - or sth, I'm not totally sure.)
3. change group ownership of all files in HDFS. (hadoop dfs
With this configuration, any user having that group name will be able
to write to any location..
(I've tried this in local network, though)

Good morning everyone,
I have a question about correct setup for hadoop. I have 14 Dell
computers in a lab. Each connected to the internet and each
independent of each other. All run CentOS. Logins are handled by NIS.
If userA logs into the master and starts the daemons and UserB logs

Like Amar said. Try adding
property
namedfs.permissions/name
valuefalse/value
/property
to your conf/hadoop-site.xml file (or flip the value in hadoop-default.xml),
restart your daemons and give it a whirl.
cheers,
