我试图在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

下面给出了参考环境参数 . 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的/ Hadoop的AUTH-2.0.0-cdh4.2.0.jar; /usr/lib/hadoop-0.20-mapreduce/ .; 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 .
