NOTE : OS used - Windows 7
So let's get started.
First of all go to the Microsoft Big Data page, and click on the Download HDInsight Server link (shown in the blue eclipse). You will see something like this :
Once you click the link it will guide you to the Download Center. Now, go to the Instructions heading and click on Microsoft Web Platform Installer.
This will automatically download and install all the required thing.
Once the installation is over open the Microsoft Web Platform Installer and go to the Top Right corner of the Microsoft Web Platform Installer UI where you will find a Search Box. Type Hadoop in there. This will show you Microsoft HDInsight for Windows Server Community Technology Preview bar. Select it and click on install. And you are done.
NOTE : It may take some time to install all the necessary components depending upon your connection speed.
On successful completion of HDInsight you can find the Hadoop Command Line icon on your desktop. Also you will find a brand new directory named Hadoop inside your C drive. This indicates that everything was OK and you are good to go.
It's time now to test HDInsight.
Step1. Go to the C:\Hadoop\hadoop-1.1.0-SNAPSHOT\bin directory :
Step2. Now, start the daemons using start_daemons.cmd :
It will show you something like this on your terminal :
This means that your Hadoop processes have been started successfully and you are all set.
Let us use few of the Hadoop Commands to get ourselves familiar with Hadoop.
1. List all the directories, sub-directories and file present in Hdfs. And we do it using fs -ls :
2. Create a new directory inside Hdfs.We use fs -mkdir to do that :
You would have become familiar with the Hadoop shell by now. But I would suggest to go to the official Hadoop Page and try more in order to get a good grip. HAPPY HADOOPING..!!
