We use Apache Hadoop and Apache HBase in several areas from social services to structured data storage and processing for internal use. We currently have about 30 nodes running HDFS, Hadoop and HBase in clusters ranging from 5 to 14 nodes on both production and development. We plan a deployment on an 80 nodes cluster. Apache Hadoop is a framework for running applications on large clusters built of commodity hardware. The Hadoop framework transparently provides applications for both reliability and data motion.

The Hadoop framework transparently provides applications both reliability and data motion. Hadoop implements a computational paradigm named Map/Reduce , where the application is divided into many small fragments of work, each of which may be executed or re-executed on any node in the cluster.

The Apache Hadoop software library is a framework that allows for the distributed processing of large data sets across clusters of computers using simple programming models. Apache Hadoop's MapReduce and HDFS components were inspired by Google papers on MapReduce and Google File System. [14] The Hadoop framework itself is mostly written in the Java programming language , with some native code in C and command line utilities written as shell scripts .
