Uploading and Retrieving images on Google Cloud Storage

You would already be aware that there are multiple options given by Google Cloud Platform to store data. Here is  Google documentation  on when to use which option: Google recommends using Google Cloud Storage (GCS) to store static content like files/videos etc. There is something called 'Blobstore' as well which is also used to store such content but it is on the way to being deprecated. This page talks about using GCS to store images. Look at  this page  to understand basic requirements for setup of GCS. In the Cloud Store Browser below following buckets are already available. If you select any bucket, you would be able to see the objects created in it.  Here you can see the image file in the 'jda-pd-slo-sandbox.appspot.com' bucket.

Hadoop for beginners, by a beginner (Part 1) - Using Cloudera Quickstart VM

You might also have read about Hadoop and Map/Reduce. But now what? How do you begin? Theory is not going to cut it, right? You want to get your hands dirty and write some code and setup some clusters, right? Right. So let's start. Admittedly, Hadoop is intimidating. Apart from having a plethora of software (first of all, you need a Linux box!) you also need to have a 'cluster' of machines because Hadoop running on one machine is not really what a real life Hadoop installation looks like. As a beginner you would like to quickly write a 'Hello World' of Hadoop rather than setting up environment. Easiest way to start instantly is using Cloudera's Quickstart VM for Hadoop.(Cloudera is one of the three biggest Hadoop distributors). First of all we need to install a virtu
