在使用Sqoop把MySQL数据导入到Hive中的时候报了一个错：
ERROR tool.ImportTool: Import failed: java.io.IOException: java.lang.ClassNotFoundException: org.apache.hadoop.hive.conf.HiveConf at org.apache.sqoop.hive.HiveConfig.getHiveConf(HiveConfig.java:50) at org.apache.sqoop.hive.HiveImport.getHiveArgs(HiveImport.java:392) at org.apache.sqoop.hive.HiveImport.executeExternalHiveScript(HiveImport.java:379) at org.apache.sqoop.hive.HiveImport.executeScript(HiveImport.java:337) at org.apache.sqoop.hive.HiveImport.importTable(HiveImport.java:241) at org.apache.sqoop.tool.ImportTool.importTable(ImportTool.java:537) at org.apache.sqoop.tool.ImportTool.run(ImportTool.java:628) 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.hadoop.hive.conf.HiveConf at java.net.URLClassLoader.findClass(URLClassLoader.java:381) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:335) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:264) at org.apache.sqoop.hive.HiveConfig.getHiveConf(HiveConfig.java:44) ... 12 more说是sqoop缺少主要的工具包去连接hive,是缺少hive-common-1.1.0-cdh5.14.2这个jar包。 解决方案： 把hive的lib目录下hive-common-1.1.0-cdh5.14.2这个jar包，拷贝到sqoop的lib目录下。
cp /opt/soft/hive110/lib/hive-common-1.1.0-cdh5.14.2.jar /opt/soft/sqoop146/lib你们的hive和sqoop安装目录位置可能和我的不一样，但都是在安装目录下的lib子目录，这个大家应该能找到，没找到的随时给我留言。
这样就能正常导数据导hive中了！
