from:http://blog.jobbole.com/83614/HBase is a NoSQL database running on Hadoop, a distributed and extensible Big Data Warehouse, which means hbase can take advantage of the distributed processing model of HDFS and benefit from the MapReduce program model of Hadoop. This means that many large tables with billions of rows and millions of columns are stored on a set of commercial hardware. In addition to the a

HBase Data Sheet IntroductionThe HBase database is a distributed, column-oriented, open-source database that is primarily used for unstructured data storage purposes. Its design ideas come from Google's non-open source database "BigTable".HDFS provides the underlying storage support for HBase, and MapReduce provides computing power for ZooKeeper, which provides a

HBase is a distributed, column-oriented open source database based on Hadoop. It uses Google's BigTable as its prototype. High Availability, high performance, column storage, scalability, real-time read/write. Fully Distributed HBase installation is based on fully distributed Hadoop installation. HBase versions and Hadoop versions must be matched.

Hbase is an open-source implementation of Google bigtable. It uses hadoop HDFS as its file storage system, hadoop mapreduce to process massive data in hbase, and zookeeper as a collaborative service.1. IntroductionHbase is a distributed, column-oriented open-source database. It originated from Google's paper bigtable: a distributed storage system for structured data. Hb
