【求助】如何学习hadoop

http://cs.smith.edu/dftwiki/index.php/Hadoop_Tutorial_2.2_--_Running_C%2B%2B_Programs_on_Hadoop Although the Hadoop framework is implemented in JavaTM, Map/Reduce applications need not be written in Java. Hadoop Streaming is a utility which allows users to create and run jobs with any executables (e.g. shell utilities) as the mapper and/or the reducer. Hadoop Pipes is a SWIG- compatible C++ API to implement Map/Reduce applications (non JNITM based). 只用java试过一些WordCount之类简单程序，不过一般来说编程语言都不会是大问题，BD~ 【 在 Wait123 (Wait123) 的大作中提到: 】 : 自己只会C/C++,但是hadopp使用java写的，虽然也支持其他语言，买了本《hadopp权威指南》大部分也是以java为例，又不是很想学java，想问问有没有只会C++的又学过hadopp的，有啥资料没？先谢过了

会C++还怕不会java吗？我倒是觉得学java的成本比用c++访问hadoop的成本低。
