Question

我正在使用Eclipse构建hadoop插件 hadoop版本是1.0.4 当我使用ant builder时，我得到如下错误

compile:
 [echo] contrib: eclipse-plugin
[javac] /home/shijieru/Downloads/HadoopInstall/hadoop-1.0.4/src/contrib/eclipse-plugin/build.xml:61: warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds

有谁能告诉我这些问题可能是什么原因？ THX

似乎你的问题不是特定于hadoop，但目录权限 - '无法创建父目录'由javac输出 - 确保你对正在编译的bin目录有适当的权限。
