Want to know hbase architecture? we have a huge selection of hbase architecture information on alibabacloud.com
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
I. Preface Over the past year, I have been busy with business analysis and top-level design for specific projects, and have little time and effort to focus on specific technical details. In addition to the improvement of architecture concepts and analysis capabilities, at the specific technical level, there has not been much progress. For some reason, I was always asked about some technical details, and many details were blurred. Take some time to rev
The company HBase (CDH-4.6.0) recently encountered a troublesome problem, and felt it necessary to document the whole process of the settlement.cause of the problemThe user failed while running the MapReduce task, reading the file from HDFs to write to HBase table (this is a mapred capability provided by HBase). This problem was found in the a environment (a test

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
