Comparing the Hadoop installations for different organisations can be fun. The investment of a company can be inferred from the size of the installation. This also shows that big data products are bought from these vendors. Facebook has the maximum number of nodes for the Hadoop cluster as per the research study conducted during 2013. Yahoo and LinkedIn also have a large number of nodes. Hadoop clusters are also run in cloud for certain small organisations. I this article sizes are compared by number of nodes for the Hadoop clusters. They act as a specific data points for the same reason. The sizes can be compared with the help of CPU scores and data volume sizes.
Certain big companies like Google uses its own clusters for file system and Map Reduce. Hence these companies have large number of clusters to organize and analyse the data in a computational environment. It boosts the speed for data analysis. The applications are highly robust and scalable. As these cluster nodes can be increased to increase the throughput performance. These Hadoop clusters are also resistant to any failure and data loss as the data backup is maintained on the clusters to support redundancy. The network interconnects them for maintaining such system for redundancy. By this way the data sciences have gained competency in the market and is developing very fast. The Hadoop system is schema less that ensures absorption of any type of data. Commodity servers have got parallel computing facility. There has been sizeable decrease in the cost due the schema less structure. Hence these advantages have led to their implementation by large scale organisations. Big Data Hadoop is the heart of data analytics and the market requires skilled professionals for data analytics.
