Hadoop Big data
Hadoop is an open source, Java based framework used for storing and processing big data. The data is stored on inexpensive commodity servers that run as clusters. ... Cafarella, Hadoop uses the MapReduce programming model for faster storage and retrieval of data from its nodes.Why is Hadoop used for big data?
Hadoop is the best solution for storing and processing big data because: Hadoop stores huge files as they are (raw) without specifying any schema. High scalability - We can add any number of nodes, hence enhancing performance dramatically. High availability - In hadoop data is highly available despite hardware failure.
