Hive is built on Hadoop and uses Hadoop's storage and execution modules. In my last post, I described a few Java based Hadoop Map-Reduce solutions from the Hadoop in Action (HIA) book. By default, hive operations are limited to the superuser. Apache Hadoop is ideal for organizations with a growing need to process massive application datasets. If you are using cdh, then the superuser is hdfs. VSkills sends you "Hadoop in Action" book. But please buy or steal from someone (like I did) "Hadoop the Definitive guide" from ORielly publishers. It is a good starting point, no argument there. Hadoop支持非java预言来编写程序，这就会用到Streaming的通用API。HadoopStreaming使用流与程序进行交互。从STDIN输入数据，输出到STDOUT。数据必须为文本，而且每一行被视为一条记录。 用Streaming处理键-.. In terms of storage Hive can use any file system supported by Hadoop, although HDFS is by far the most common. January 18, 2011 Dreamtech Press Leave a comment Go to comments. The reason for this is because of the permission of hive warehouse directory. Today, we While Pig is very versatile and extensible, there are certain tasks that are better performed elsewhere (some of which are specific to the data processing platform, Hadoop).
