Design and implementation of data mining and data migration system under Hadoop architecture Shanghai Jiao Tong University Lu Ming Education usually the enterprise's information system will contain multiple business systems, each business system contains its own set of online business system, backup system and filing system, system management is complex, easy to cause the waste of storage space, And the system scalability is poor. In view of the above shortcoming, this paper designs and realizes a tiered storage system, uses a large data platform to carry on the unified management to the multiple business system data, unifies each business system backup system and the filing system. This Part ...
The increasing volume of data and the increasing competitive pressures have allowed more and more enterprises to start thinking about how to tap the value of these data. Traditional BI systems, http://www.aliyun.com/zixun/aggregation/8302.html > Data warehouses and database systems do not handle this data well. Reasons include: 1. The data volume is too large, the traditional database can not effectively store and maintain acceptable performance; 2. The newly generated data are often unstructured, while traditional parties ...
Cloudera's idea of Hadoop as an enterprise data hub is bold, but the reality is quite different. The Hadoop distance has a long way to go before other big data solutions are eclipsed. When you have a hammer big enough, everything looks like nails. This is one of the many potential problems that Hadoop 2.0 faces. For now, the biggest concern for developers and end-users is that Hadoop 2.0 has massively modified the framework for large data processing. Cloudera plans to build Hadoop 2.0 ...

Analysis is the core of all enterprise data deployments. Relational databases are still the best technology for running transactional applications (which is certainly critical for most businesses), but when it comes to data analysis, relational databases can be stressful. The adoption of an enterprise's Apache Hadoop (or a large data system like Hadoop) reflects their focus on performing analysis, rather than simply focusing on storage transactions. To successfully implement a Hadoop or class Hadoop system with analysis capabilities, the enterprise must address some of the following 4 categories to ask ...
With the start of Apache Hadoop, the primary issue facing the growth of cloud customers is how to choose the right hardware for their new Hadoop cluster. Although Hadoop is designed to run on industry-standard hardware, it is as easy to come up with an ideal cluster configuration that does not want to provide a list of hardware specifications. Choosing the hardware to provide the best balance of performance and economy for a given load is the need to test and verify its effectiveness. (For example, IO dense ...
There is no doubt that big data has become a buzzword for 2012 years. Large data processing has reached $70 billion trillion this year and is growing at an annual rate of 15–20%, according to reports from foreign statistical agencies. Almost all major tech companies are interested in large data and have invested heavily in the products and services in this area. These include IBM, Oracel, EMC, HP, Dell, SGI, Hitachi, Yahoo, and so on, and the list continues. IBM also released a large data processing and analysis technology in mid-2011: ...
Using Hadoop to drive large-scale data analysis does not necessarily mean that building a good, old array of distributed storage can be a better choice. Hadoop's original architecture was designed to use a relatively inexpensive commodity server and its local storage in a scale-out manner. Hadoop's original goal was to cost-effectively develop and utilize data, which in the past did not work. We've all heard of words like large-scale data, large-scale data types, large-scale data speeds, etc. that describe these previously unmanageable data sets. Given the definition so ...
The hardware environment usually uses a blade server based on Intel or AMD CPUs to build a cluster system. To reduce costs, outdated hardware that has been discontinued is used. Node has local memory and hard disk, connected through high-speed switches (usually Gigabit switches), if the cluster nodes are many, you can also use the hierarchical exchange. The nodes in the cluster are peer-to-peer (all resources can be reduced to the same configuration), but this is not necessary. Operating system Linux or windows system configuration HPCC cluster with two configurations: ...
1 Overview HBase is a distributed, column-oriented, extensible open source database based on Hadoop. Use HBase when large data is required for random, real-time reading and writing. Belong to NoSQL. HBase uses Hadoop/hdfs as its file storage system, uses Hadoop/mapreduce to deal with the massive data in HBase, and uses zookeeper to provide distributed collaboration, distributed synchronization and configuration management. HBase Schema: LSM-Solve disk ...
