Different flavours of Hadoop?

There are so many flavors of Hadoop available as Cloudera, Hortonworks etc.
The nice thing is that you can download and try a free version. The base Apache distribution is good when you are just learning and getting started. 

The real advantage of the bundled distributions such as Cloudera and Hortonworks is that you don't have to think about version x of Hive will work with Hadoop version y and version z of Hbase.

They also come with better tools for deployment and management in an operational environment for example Cloudera comes with Cloudera Manager which provide you the web GUI for everything.

There are three modes to start a Hadoop cluster.

1.      Local (Standalone) Mode

2.      Pseudo-Distributed Mode
3.      Fully-Distributed Mode

In next post will start with Cloudera Quickstart VM and will see how to install in Virtual Machine.

All of this unstructured data is Big Data. When dealing with larger data sets, organizations face difficulties in being able to create, manipulate, and manage big data. Big data is particularly a problem in business analytics because standard tools and procedures are no...
