Install Hadoop on Linux Pseudo Distributed Mode - Root Required?
Hi,
I am planning to install Hadoop on Linux in a Pseudo Distributed Mode ( One Machine ). Do I require 'root' privileges for install ? Please advise.
Thanks,
Raj

CDH is also available as tarball. So if you are planning to do tarball
installation. No root privilege is required. You can install it completely
including java. But make sure that the necessary ports in the machine are
open.
If you are planning to do a package installation, you need root privileges.
But these root permission are just for installation only.

Raj,
Apache Hadoop by itself does not require root privileges to run
(assuming a non-secure setup). You can run it out of a tarball from a
home directory you have on the server machines.
However, many prefer using packages, such as those from Apache
Bigtop/etc., to install Hadoop and use it. This facilitates easier
upgrades and is closer to the regular management/administration of an
OS. Installing packages in an OS requires root-level permissions due
to the kind of paths it touches. Root isn't a user that will run the
services in the end, however.
The only real reason you need root to actually run the cluster is when
you set it up for security and you'd need to start the DN over
reserved ports. In this case, we need the DN to start as root, but
post-port-bind we switch back down to the actual user.

So for CDH, while installing - how do i request my Unix admin ? Any tips.
I am requesting a separate user on Linux box. So how do that user ( what kind of privileges ) are required for the new user? and do these new user need to have some kind of temporary root access. How does this work between a person who is installing Hadoop and the actual unix admin guy. Please advise.

Hello Raj,
Install in what sense?Are you planning to use Apache's package?If that is the case you just have to download and unzip it. And you don't need root privilege for that.Or something else like CDH?I'm sorry, I didn't quite get the question.
Warm Regards,

You do not root if you want to install everything in your home directory
and assuming sun jdk is installed

Raj,
Apache Hadoop by itself does not require root privileges to run
(assuming a non-secure setup). You can run it out of a tarball from a
home directory you have on the server machines.
However, many prefer using packages, such as those from Apache
Bigtop/etc., to install Hadoop and use it. This facilitates easier
upgrades and is closer to the regular management/administration of an
OS. Installing packages in an OS requires root-level permissions due
to the kind of paths it touches. Root isn't a user that will run the
services in the end, however.
The only real reason you need root to actually run the cluster is when
you set it up for security and you'd need to start the DN over
reserved ports. In this case, we need the DN to start as root, but
post-port-bind we switch back down to the actual user.
