Hadoop 3.0 在Mac上面编译失败

时间：2015年4月

Hadoop版本：当前日期trunk最新版

OS版本：OS X 10.10.2

编译错误：

当编译hadoop-mapreduce-client-nativetask 3.0.0-SNAPSHOT工程的时候会出错，错误如下：

该错误显示找不到__debug文件，在该路径下确实没有该文件/Library/Developer/CommandLineTools/usr/include/c++/v1/__debug
搜索了一下发现是由于最近更新了Command Line Tools 6.3所致，最近OS推送了这个更新，我也更新了，但是该版本貌似不那么友好，所以出现了该编译错误。

规避解决方法：

回退该工具到6.2版本，下载地址：https://developer.apple.com/downloads/index.action

选择Command Line Tools(OS X 10.10) for Xcode - Xcode 6.2版本
