问题：

Sqoop连接数据库报错，报错信息为：

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/lang/StringUtils at org.apache.sqoop.manager.MySQLManager.initOptionDefaults(MySQLManager.java:73) at org.apache.sqoop.manager.SqlManager.<init>(SqlManager.java:89) at com.cloudera.sqoop.manager.SqlManager.<init>(SqlManager.java:33) at org.apache.sqoop.manager.GenericJdbcManager.<init>(GenericJdbcManager.java:51) at com.cloudera.sqoop.manager.GenericJdbcManager.<init>(GenericJdbcManager.java:30) at org.apache.sqoop.manager.CatalogQueryManager.<init>(CatalogQueryManager.java:46) at com.cloudera.sqoop.manager.CatalogQueryManager.<init>(CatalogQueryManager.java:31) at org.apache.sqoop.manager.InformationSchemaManager.<init>(InformationSchemaManager.java:38) at com.cloudera.sqoop.manager.InformationSchemaManager.<init>(InformationSchemaManager.java:31) at org.apache.sqoop.manager.MySQLManager.<init>(MySQLManager.java:65) at org.apache.sqoop.manager.DefaultManagerFactory.accept(DefaultManagerFactory.java:67) at org.apache.sqoop.ConnFactory.getManager(ConnFactory.java:184) at org.apache.sqoop.tool.BaseSqoopTool.init(BaseSqoopTool.java:272) at org.apache.sqoop.tool.ListDatabasesTool.run(ListDatabasesTool.java:44) at org.apache.sqoop.Sqoop.run(Sqoop.java:147) 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:382) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher $AppClassLoader.loadClass(Launcher.java:349) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ... 20 more

解决方法：

在apache 上下载commons-lang-2.6.jar包并上传到lib下即可，下载地址：http://mirrors.tuna.tsinghua.edu.cn/apache//commons/lang/binaries/commons-lang-2.6-bin.zip
