4922.构建一个蜂巢式的数字图书馆
[信息传输、软件和信息技术服务业] [2013-12-20]
Storing massive amounts of data is great until you need to do something with it. No incredible discoveries or futuristic predictions come from unused data, no matter how much of it you store. Big data can be a complicated beast. Writing complex MapReduce programs in the Java programming language takes time, good resources, and know-how that most organizations don't have available. This is where building a data library using a tool like Hive on top of Hadoop becomes a powerful solution.

4923.Sqoop:NoSQL和RDBMS之间的大数据管道
[信息传输、软件和信息技术服务业] [2013-12-20]
Sqoop is an integral part of the Hadoop ecosystem, helping transfer the data between NoSQL data storage and the traditional RDBMS. Numerous technical articles have been published featuring the Sqoop command-line interface usage. However, as of Sqoop 1.4.3, there is not much insight publicly available on the usage of the Sqoop Java? API. This article covers the usage of the Sqoop CLI with additional emphasis on the Sqoop Java API, using an example of data from the Bombay Stock Exchange. The article is intended to provide preliminary exposure to technical architects, solution architects, technical managers, consultants, data scientists, technical leads, and developers interested in and working in the big data space.

4924.测量二维电子密度分布在低电流电弧的外磁场下使用夏克-哈特曼型激光波前传感器
[计算机、通信和其他电子设备制造业] [2013-12-20]
Applying external magnetic fields to arc discharges in gas circuit breakers is very helpful for facilitating arc extinguishing process. However, there has never been a report on decreases in arc electron densities under external magnetic fields. Here, 2-dimensional electron density distribution over an arc channel under an external magnetic field were obtained by only a single measurement using a Shack-Hartmann type laser wavefront sensor. The electron densities around a gap centre of about 10~(22)m~(-3) were lower than those without external magnetic fields when an instantaneous current decreased to 20A.

4928.利用企业Hadoop的好处
[信息传输、软件和信息技术服务业] [2013-12-20]
MapReduce implementations are the technology of choice for enterprises that want to analyze big data at rest. Businesses have a choice between purely open source MapReduce implementations — most notably, Apache Hadoop — and commercial implementations. Here, the authors argue the case that enterprise requirements are better served by Hadoop-based products, such as InfoSphere? BigInsights? than they are by "vanilla" Hadoop.
