Study of Apache Hadoop
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 2014, Vol 3, Issue 12
Abstract
Apache Hadoop is an open-source software framework for distributed storage and distributed processing of Big Data on clusters of commodity hardware. . The settings for the Hadoop environment are critical for deriving the full benefit from the rest of the hardware and software. The Distribution for Apache Hadoop* software includes Apache Hadoop* and other software components optimized to take advantage of hardware-enhanced performance and security capabilities.The Apache Hadoop project defines HDFS as “the primary storage system used by Hadoop applications” that enables reliable ,extremely rapid computations. Its Hadoop Distributed File System (HDFS) splits files into large blocks (default 64MB or 128MB) and distributes the blocks amongst the nodes in the cluster. Hadoop uses a distributed user-level filesystem. It takes care of storing data -- and it can handle very large amount of data.
