运行sqoop时找不到类异常：org / apache / sqoop / Sqoop
[英]Class not found exception while running sqoop: org/apache/sqoop/Sqoop
问题描述
I 've installed sqoop on a machine (sqoop-1.4.4.bin__hadoop-1.0.0.tar.gz from http://www.apache.org/dist/sqoop/1.4.4/ ). 
我已经在计算机上安装了sqoop（来自http://www.apache.org/dist/sqoop/1.4.4/的 sqoop-1.4.4.bin__hadoop-1.0.0.tar.gz）。 When I try to run "$SQOOP_HOME/sqoop help" or any other command for that matter, 当我尝试运行“ $ SQOOP_HOME / sqoop help”或任何其他命令时，
I am receiving the following error: 我收到以下错误：
Warning: $HADOOP_HOME is deprecated.
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/sqoop/Sqoop Caused by: java.lang.ClassNotFoundException: org.apache.sqoop.Sqoop at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:247) Could not find the main class: org.apache.sqoop.Sqoop.
I tried installing sqoop in other machines and it worked fine. 我尝试在其他计算机上安装sqoop，效果很好。 But not in one particular machine I want :( I've set hadoop home path and also have sqoop home in classpath. 但是我不想在一台特定的机器上:(我设置了hadoop home路径，并且在classpath中也有sqoop home。
Could someone let me know where am I doing mistake? 有人可以让我知道我在哪里做错吗？

不要在类路径中设置Sqoop主页，而在类路径中设置sqoop lib，如下所示：
export CLASSPATH=$CLASSPATH:$SQOOP_HOME/lib
