Question

作为初学者尝试hadoop，我指的是this article用于设置单个节点独立的hadoop实例。我相信我的路径变量都设置得很好，但是当我尝试运行时

$ bin/hadoop jar hadoop-examples-*.jar grep input output 'dfs[a-z.]+'

JVM崩溃。

[root@test hadoop-1.2.1]# ./bin/hadoop jar hadoop-examples-1.2.1.jar grep input output 'dfs[a-z.]+'

我不是分析错误日志的专家，但如果有任何具体要求，我可以提供相关细节。

如果打印版本表明路径设置正常：

[root@test hadoop-1.2.1]# ./bin/hadoop -version
java version "1.6.0_06"
Java(TM) SE Runtime Environment (build 1.6.0_06-b02)
Java HotSpot(TM) Server VM (build 10.0-b22, mixed mode)

我正在使用运行在具有2GB内存的Intel Xeon处理器上的Linux机器上。除了确保java路径之外，是否还需要进行其他配置？

编辑：在link here上载了文本文件，因为我不知道日志的哪个部分会有用。我也尝试了另一个java版本但结果相同

[root@f4mail hadoop-1.2.1]# ./bin/hadoop -version
java version "1.6.0_31"
Java(TM) SE Runtime Environment (build 1.6.0_31-b04)
Java HotSpot(TM) Server VM (build 20.6-b01, mixed mode)
