full insight of the spark and crystal details of its usage. hadoop is an open source frame work used for storing & processing large-scale data (huge data sets generally in gbs or tbs or pbs of size) which can be either structured or unstructured format. this vast amount of data is called big data which usually can’t be hadoop is written in ja*a by apache software foundation. hadoop can easily handle multi tera bytes of data reliably and in fault-tolerant hadoop parallelizes the processing of the data on 1000s of computers or nodes in clusters. this frame work uses normal commodity hardware for storing distributed data across various nodes on the cluster. this site provides detailed walk through of the hadoop framework along with all the sub components under hadoop frame work. refer corresponding categories on this blog for further details on each sub component of hadoop eco system. now a day the electronic data is getting increased rapidly day by day in terms of tera bytes (1000 gb = 1 tb) or peta bytes (1000 tb = 1 pb) all over world. this data is majorly stored on databases, distributed across the globe. the rate of data increase is getting accelerated. some of the data might be structural and some might be unstructured data like flat data sets. some of the examples of huge data generations sources are like social networking sites, blogs, databases and many other kinds of web sites. this data is being used by various. but extraction & an*lysis of vast amount of structured data or unstructured data requires lot of computational power which is beyond. the scope of legacy databases or processing techniques. this mas*ive explosion of data over the years leads many organizations to replace the data servers with high processing servers which couldn’t solve the problem beyond a certain point of growth in data. that’s where the hadoop evolution started based on scale-out approach for storing big data on large clusters of commodity hardware. since hadoop is designed to use commodity hardware through scale-out approach instead of using the larger servers in scale-up approach,
