Cloud Foundry Test - 2

Continuing from where we left off in Cloud Foundry Test - 1...

.. with the latest version of Fedora, I was not able to install rubygems ... so I downloaded and installed vs 1.3.2 (dont know why, probably a stale post I read)... after managing to install Gem I ran the following (http://rubygems.org/pages/download):

gem update --system

...which worked ok... so where were we???
Following the vmc Getting Started instructions in YouTube (http://www.youtube.com/watch?v=dqr8xWQlRcM)

ruby -v (check)
gem -v (I had 1.8.3 with some deprecated components)
sudo gem update --system (already done as above)

sudo gem install vmc (!!!)

Connect to api.cloudfoundry.com
vmc target api.cloudfoundry.com (will receive ok)

Now login to cloudfoundry
vmc login (using the temp password)
vmc passwd (to reset the password)

Write a small ruby application
require 'sinatra'
get '/' do
"Hello from Cloud Foundry - sedatiko's account"
end
Go into the directory you have the code and run...
vmc push
picked hello as the application name, it detected that this was a Sinatra application!
Memory reservation: 64M (just a test)
got the following error:
Creating Application: Error 702: External URIs are not enabled for this account
I believe this was due to the fact that "hello.cloudfoundry.com" was "taken"... tried again with sedatiko and...
Creating Application: OK
Would you like to bind any services to 'sedatiko'? [yN]:

Windows 7 Do NOT Remember folder settings

There used to be an option in prior windows version where under Folder Options, you would "NOT remember" the view settings. This way, the browsing would be uniform, unless you wanted to change it. I found a way to do it in Win 7. Go to Folder Options\View and click Apply to Folders. This will apply the view in the current window to all folder views.

The purpose is to create a disk to keep contents shared across the VMs Following the instructions at http://www.vmware.com/support/ws45/doc/ws40_disks.html#1046465 Find your VM installation and run the following C:\Program Files\VMware\VMware Workstation> vmware-vdiskmanager.exe  -s 10GB -a ide -t 1 -c "D:\Virtual Machines\vmDisk.vmdk" (s: size, a: interface, t: type (0-3 for increase and size options), c:create) Creating disk 'D:\Virtual Machines\vmDisk.vmdk'   Virtual disk creation successful. How to browse a Vmdk? http://www.vmware.com/support/ws45/doc/disks_add_ws.html#1008949 Tried to add this newly created disk when the vm server was on by going to settings/add/hard drive/existing virtual.

Big Data & Hadoop

Since everything moves fast in the IT world, you have new terminologies entering their 3rd or 4th generation by the time you get a chance to get your hands dirty with them. Big Data has been one of them, an alluring technology allowing massive distributed power over large datasets using the famous map-reduce algorithm. Apache Hadoop allows scaling to massive proportions and has been in use with tech giants like Google and Facebook. I decided to start running a Hadoop cluster myself using the following guide as a started. https://github.com/GoogleCloudPlatform/solutions-google-compute-engine-cluster-for-hadoop/blob/master/README.md This version installs Hadoop locally but uses the Google App Engine and Google Cloud Storage  and allows basic scaling/clustering. I started running the pre-requisites on a VM Centos 6.4 and things were going ok. Then I realized that I needed to go deeper into Hadoop and maybe run a sample locally, without achieving the Cloud version first. ...
