本文介绍了与Hadoop交互的四种主要方法：Native Libraries、Hive、Pig和Cascading。Native Libraries提供最佳性能和最精细的控制；Hive提供类似SQL的语言；Pig介于Hive的SQL式语言和Cascading的Java式语言之间；Cascading则提供了更接近Java的编程体验。
和Hadoop交互的四种方法：
1. Native Libraries
2. Hive
3. Pig
4. Cascading
At a high level, people use the native Hadoop libraries to achieve the greatest performance and have the most fine-grained control. Pig is somewhere between the very SQL-like, database language provided by Hive and the very Java-like programming language provided by Cascading. - See more at: http://blog.gopivotal.com/pivotal/products/hadoop-101-programming-mapreduce-with-native-libraries-hive-pig-and-cascading#sthash.h7JxtIq3.dpuf
