Distributed Database HBase

Http://www.aliyun.com/zixun/aggregation/13713.html ">hbase–hadoop Database is a highly reliable, high-performance, column-oriented, scalable, distributed storage system, Using hbase technology, large structured storage clusters can be built on inexpensive PC servers.
HBase is an open-source implementation of Google BigTable, similar to Google BigTable leveraging GFs as its file storage system, hbase using Hadoop HDFs as its file storage system Google runs mapreduce to handle massive amounts of data in BigTable, HBase also uses Hadoop mapreduce to handle massive amounts of data in HBase, and Google BigTable uses chubby as a collaborative service, HBase uses zookeeper as its counterpart.

The above illustration depicts the layers of systems in the Hadoop ecosystem, where HBase is located at the structured storage layer, and the Hadoop HDFs provides a high level of reliable underlying storage support for HBase, and Hadoop MapReduce delivers high-performance computing power for HBase, Zookeeper provides stable service and failover mechanism for hbase.
In addition, pig and Hive also provide high-level language support for hbase, making it very easy to perform data statistics processing on hbase. Sqoop provides a convenient RDBMS data import function for HBase, which makes it easy to migrate traditional database data to hbase.
