You can put this parameter to core-site.xml or hdfs-site.xml
It both parsed during the HDFS startup.

No, it is not called "pseudo distributed" mode. It called "as you wish"
mode...
It is absolutely normal configuration.
You can distribute your nodes as you like, no one limit you on it.
Just make sure you have enough memory on your nodes.
If you have more questions, feel free to s=ask it directly.
What is the reason?
Could you explain in more details, what do you want to accomplish?
Leonid.

You definitely can.
Just set rack script on your VMs.

Make sure your mapred.local.dir (check it in mapred-site.xml) is actually
exists and writable by your mapreduce usewr.
Thank you!

Yusaku,
You are absolutely right.
This is the only correct format for /etc/hosts:
x.x.x.x Full_Nameshort_name(alias)
Any other forms of it is incorrect and may lead to unpredictable results.

Oleg,
why don’t you talk to me?
Put 1 ZK and 1 JN on NN boxes, third one on one of the data nodes.
HA wizard will automatically remove SNN from your cluster and put second NN in
it’s place instead.
If something does not work as you expected, give me a call.
Thank you!
