在java中调用sqoop接口进行mysql和hdfs直接数据传输时，遇到以下错误： Found interface org.apache.hadoop.mapreduce.JobContext, but...class was expected 这里需要注意，sqoop有两个版本： sqoop-1.4.4.bin__hadoop-1.0.0.tar.gz（对应hadoop1版本） sqoop-1.4.4....bin__hadoop-2.0.4-alpha.tar.gz（对应hadoop2版本） 出现上面的错误就是hadoop和对应的sqoop版本不一致，二者保持一致即可解决问题。

1 Hadoop Configuration简介 Hadoop没有使用java.util.Properties管理配置文件，也没有使用Apache Jakarta Commons Configuration...管理配置文件，而是使用了一套独有的配置文件管理系统，并提供自己的API，即使用org.apache.hadoop.conf.Configuration处理配置信息。 ...org.apache.hadoop.conf目录结构如下： ? 2 Hadoop配置文件的格式解析 Hadoop配置文件采用XML格式，下面是Hadoop配置文件的一个例子： <?...测试程序如下： /** * @Title ConfigurationTest.java * @Package org.apache.hadoop.conftest * ...; import org.apache.hadoop.conf.Configuration; import org.apache.hadoop.fs.Path; public class ConfigurationTest

想在 IDEA 上运行 Hadoop 的单测，以为 Maven 相关的依赖和插件下载好就能跑了是吧？...果不其然，没那么简单，下面就收到一个报错了: org.apache.hadoop.ipc.xxx不存在，见下图。 ? 上面显示的这个是什么包？为什么会报这个错呢？...其实不用着急，只要你了解 Hadoop 底层，有点后端的基础，慢慢推敲一下。看到 RPC，那么可以理解，这些不存在的文件为什么不存在呢？
