I have three laptops(with ubuntu) that I am networking to act as a cluster for hadoop. I also have a windows only machine, is it possible to add that to the cluster and make it act as a node? Is it feasible? Has anyone come across such an issue?
If you have windows environment, I would suggest that you use VirtualBox and any Linux as Guest OS.
You can build your Hadoop cluster on that. There are numerous installation procedures available for Linux and you can't go wrong with that.
We are using it exactly this way for development purposes. Performance of Hadoop cluster is not a concern as is the functionality.
It also allows you to fine tune your dev ops since you can tear apart and start afresh with a new VM.
Easiest approach to build this way is to :
Install VirtualBox
Install Vagrant
Use a community provided box from: http://www.vagrantbox.es/
Bootstrap your VM for yum packages
Move from NAT interface to Bridged Ethernet interface
Install Hadoop using SCM: http://www.cloudera.com/products-services/tools/
Bring up your cluster
Yes it is possible. On the ubuntu machines, Hadoop installation should be straightforward, you just need to follow the regular steps. Since Hadoop runs on Linux environment, you need to install Cygwin on your windows Machine which is a Linux-like environment for Windows, and will enable you to install and run Linux-based applications (like hadoop) on a Windows machine.
Here is the link for Cygwin Installation: http://www.cygwin.com/install.html

I have a school project that requires Hadoop installation (It is basically so we get familiar with it. I don't see it needing further applications). Would you recommend installing it on my computer (I have a mac with M1) or using parallels and installing it in a windows VM?
TIA
I would definitely not recommend a Windows environment for Hadoop, virtual or not.
If it's a throw away environment, a VM (or Docker setup) would be preferred. However, it's easiest installed directly on the host (brew install hadoop), and will therefore have full access to your machine for multi threading.
Alternatively, cloud providers offer schools deep discounts, and a cluster of several machines is a few clicks away rather than needing to tune everything just for your one machine.
Do I get less features or functions of hadoop env. when installed on windows machine using virtual box? Is is good to have this sort of hadoop installation for beginners practice? or What is the difference when hadoop in installed on linux machine vs installation on virtual box on a windows machine.
You can have fully distributed cluster on your windows machine using multiple nodes in the virtual box . However for beginners I will recommend you set up a single node cluster and do the practice. There is no thing as such that you will get less features . You will be running pseudo distributed mode of hadoop . All the daemons will be running. Only thing is that since you have single windows machine with limited storage/ram, you cant test the cluster with huge amounts of data. Hope this helps.
I am researching Ansible and am figuring out what is required to use it in a Windows only environment. I came across this link:
http://docs.ansible.com/intro_windows.html
and there it says that I need a Linux control machine.
I don't want to make it a requirement for customers who are Windows shops to setup and manage a Linux machine. So can I run a Linux VM on a Windows machine and use that as my control machine? I haven't tried this yet but wanted to know if there are any gotchas with this approach?
Yes, you could use a Linux VM to execute your Ansible playbooks. We did this for a coworker who ran Windows-only and it works fine as long as you configure the VM to be able to SSH into the Ansible-managed servers.
Yes it can be a VM but the best thing is to use virtualenv and install ansible inside the virtualenv, which is also true on Windows machine, I think as I am not Windows user. The main banefit is that you don't need to run the VM and give it the more resources. Hope that will help you. Thanks
I have a windows 7 laptop and I need to setup hadoop (mutlinode) cluster on it.
I have the following things ready -
virtual softwares, i.e. virtualbox and vmware player.
Two virtual machines, i.e.
Ubuntu - for Hadoop master and
Ubuntu - for (1X) Hadoop slave
Has anyone done a setup of such a cluster using Virtual machines on
your laptop ?
If yes please help me to install it.
I've searched over google but I am not getting how to configure this multi-node cluster on hadoop using VMs?
How to run two Ubuntu OS on windows 7 using VMware or virtualbox?
Should we use same Ubuntu version VM image or
vm images with different versions of Ubuntu linux?
Yes you can use ubuntu two node. I am using five nodes(1 master, 4 datanodes).
If you want install multi node in vm ware.
Just download ubutnu from this link: http://www.ubuntu.com/download/desktop
And install two machine. And install java and openssh.
And download shell script for multinode from this link::
https://github.com/tonyreddy/Apache-MultiNode-Insatallation-Shellscript
And try it .....
All the best............
Since you're running Hadoop on your laptop, obviously you're doing it for learning purposes or building POC or functional debugging.
Instead of going through the hassles of installing and setting up Hadoop and related Big-Data softwares, you can simply install a pre-configured pseudo-distributed VM.
Some good options are:
Cloudera QuickStart VM
Hortonworks Sandbox
I've been using the Cloudera's VM on my laptop for quite sometime now and it's been working great.
Cloudera and Hortonworks are the fastest way to get it up and running.
Make sure you have enough RAM installed on your laptop for the Operating system already running, else your laptop will restart abruptly often while you use the Virtual machines.
Let me give you an example -
If you are using Windows 10, it needs 3-5GB RAM to be used to work smoothly,
This means if you load a Virtual Machine of 5GB size in your RAM, Windows may crash when it does not find enough RAM to operate.
You must upgrade the RAM from 8GB to 12GB or best 16GB for smooth operation of your laptop.
Hope it helps
I want to set up a hadoop environment with linux fedora as master and windows 7 machine as slave. Is this combination possible and if so, do I need to install cygwin in windows 7?
The good practice says do not run hadoop on the Windows (simple as that ).
Why do you want to do that?
In case you want to test something use pseudo distributed mode (run all hadoop services on one machine)
Additional thing, I would recommend to use some distribution of the hadoop, for instance cloudera.
This link explains step-by-step how to setup it.

This is pretty simple and what is the important, very briefly documented
