运行Sqoop是我们发现如下报错：

 Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/lang/StringUtils at org.apache.sqoop.tool.BaseSqoopTool.validateHiveOptions(BaseSqoopTool.java:1583) at org.apache.sqoop.tool.ImportTool.validateOptions(ImportTool.java:1178) at org.apache.sqoop.Sqoop.run(Sqoop.java:137) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:76) at org.apache.sqoop.Sqoop.runSqoop(Sqoop.java:183) at org.apache.sqoop.Sqoop.runTool(Sqoop.java:234) at org.apache.sqoop.Sqoop.runTool(Sqoop.java:243) at org.apache.sqoop.Sqoop.main(Sqoop.java:252) Caused by: java.lang.ClassNotFoundException: org.apache.commons.lang.StringUtils at java.net.URLClassLoader.findClass(URLClassLoader.java:381) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ... 8 more

在apache 上下载commons-lang-2.6.jar包并上传到sqoop的lib下即可，下载地址：点击下载
