试验 ? 值得一试。了解为何要构建这一能力是很重要的。企业应当在风险可控的前提下在项目中尝试应用此项技术。
Hadoop continues to be the most popular framework to develop distributed data-processing applications. Although programming Hadoop applications in Java is not particularly difficult, designing efficient MapReduce pipelines does require a good amount of experience. Apache Pig simplifies Hadoop development by offering a high level language, called Pig Latin, and an execution runtime. Pig Latin is procedural and provides a SQL-like interface to work with large datasets. The execution infrastructure compiles Pig Latin into an optimized sequence of MapReduce programs that run on the cluster. Pig Latin is extensible through user-defined functions in different languages such as Ruby, JavaScript, Python and Java.
