on each node where each source information block is stored. This enables Hadoop to handle the following large sets of information by allowing multiple nodes to process data concurrently. For example, for 100 nodes, you can process 100 log files at the same time, simplifying many gigabytes (or terabytes) of information much faster than through a single node. Hadoop Information A major limitation of core Hadoop products is the inability to store and query information in the database. The data i
