How to start learning hadoop

The easiest way to get started with Hadoop is Sandbox with VM Player or Virtual Box. It is a personal, portable Hadoop environment that comes with a dozen interactive Hadoop tutorials. Sandbox includes many of the most exciting developments from the latest CDH/HDP distribution, packaged up in a virtual environment. You can start working on hadoop environment within 10 minutes.

Hadoop Sandbox provides:

1. A virtual machine with Hadoop preconfigured.
2. A set of hands-on tutorials to get you started with Hadoop.
3. An environment to help you explore related projects in the Hadoop ecosystem like Apache Pig, Apache Hive, Apache HCatalog and Apache HBase.

Lets start downloading and installing hadoop into our windows machine in 10 mins

System requirements to run VMplayer:

RAM: at least 8 GB (For a 2-Node Virtual Cluster). Processor: i3 or above. at least 20 GB free disk space.

Step 1. Download and install VMPlayer from the following websites

After clicking on Next, the Appliance Settings are displayed.

6. Modify Appliance Settings as needed.
Within the Appliance Settings section you may wish to allocate more RAM to the
virtual appliance.  Setting 8GB of RAM to the Hortonworks Sandbox virtual appliance
will improve the performance.  Make sure you have enough physical RAM on the
host machine to make this change. To make the change, click on the specific value to
