Question

我正在尝试在CDH 4.2中启动Hive，我遇到了以下问题

hive
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/util/PlatformName
Caused by: java.lang.ClassNotFoundException: org.apache.hadoop.util.PlatformName
    at java.net.URLClassLoader$1.run(URLClassLoader.java:202)

以下是供参考的环境参数。我错过了什么吗？

echo $ HADOOP_CONF_DIR /etc/hadoop/conf/conf.pseudo

echo $ HADOOP_HOME /usr/lib/hadoop-0.20-mapreduce

echo $ CLASSPATH   /usr/lib/hadoop-0.20-mapreduce/hadoop-core.jar;/usr/lib/hadoop/hadoop-auth-2.0.0-cdh4.2.0.jar;/usr/lib/hadoop-0.20-mapreduce/ < EM> ;

echo $ HIVE_HOME

如果您想查看我在此处可能缺少的任何其他环境变量，请与我们联系。
