Most Popular Hadoop Distributions


Most Popular Hadoop Distributions

Currently there are lot of Hadoop distributions available in the big data market, but the major free open source distribution is from Apache Software Foundation. And even remaining hadoop distribution companies provide free versions of Hadoop, and also provide customized hadoop distributions suitable for client organization needs. By using Apache Hadoop as the core framework, these companies build their own customized hadoop cluster setup and services and provide commercial support for big data organizations. These are known as commercial hadoop distributions. These hadoop vendors provide services like managing updates, providing support, training, and consulting, and even adding some innovations of their own that make Hadoop reasonable for an enterprise to handle.

In Free Open Source market, Redhat is making money by taking Unix/Linux Core Kernel (an open source operating system) bundle all its required components, building a simple installer, and providing paid support to any customers.

In the same way, there are many companies which are providing enterprise editions and paid support on top of apache Hadoop distribution.

Free Open Source Hadoop Distribution

    • DSE is designed to manage real-time, enterprise search data in the same database cluster.
    • It also comes with OpsCenter Enterprise, which allows for the management DSE Clusters via a central web interface.

Apart from these, there are many other hadoop distributions but all of these are open sourced under Apache’s GNU Public License.

Comparison Chart

Below is a good comparison chart prepared by Robert Schneider, in the Hadoop Buyer’s Guide in 2014 for Cloudera, Horton Works, MapR, the three leading commercial Hadoop Distributions.

Cloudera-vs-HortonWorks-vs-MapR

By looking at the above comparison chart one may feel that MapR is better among all the three but before concluding that, we need to consider a few characteristics of it.

  • MapR has its own Proprietary File System (MapRFS), It will be painful if an organization has to switch the hadoop vendor from MapR to any other because of its own FS being different from native HDFS in other distributions.
  • Mutable Keys: The MapR file system allows mutable keys while HDFS does not.  The idea of being able to change an established key (mutability) is risky and potentially dangers the ability of all previously built applications to use the data if the keys were inadvertently changed.  MapR argues that there are actually advantages of mutability and that good data management practices eliminate this risk.

So, an organization has to review all the strengths and weaknesses of each vendor before choosing hadoop distribution for their big data business intelligence platform.
