线程"main"中的异常java.lang.NoClassDefFoundError:org/apache/hadoop/util/PlatformName

Question

我知道有关此异常的帖子很多,但我无法解决这个问题.必须编辑类路径我想解决它.我试图在hadoop基础设施中运行一个名为DistMap的程序.这是我得到的错误.

哪个java说

/usr/java/jdk1.6.0_32/bin/java

echo $ CLASSPATH给出一个空行

猫〜/ .bash_profile说

cat ~/.bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin

export PATH

更新:

$ HADOOP_HOME /usr/lib/hadoop

$ HADOOP_CLASSPATH

/usr/lib/hadoop-0.20-mapreduce/hadoop-ant-2.0.0-mr1-cdh4.4.0.jar:/usr/lib/hadoop??-0.20-mapreduce/hadoop-ant.jar:/usr/lib/hadoop-0.20-mapreduce/hadoop-examples-2.0??.0-mr1-cdh4.4.0.jar:/usr/lib/hadoop-0.20-mapreduce/hadoop-examples.jar:/usr/lib/h??adoop-0.20-mapreduce/hadoop-core.jar:/usr/lib/hadoop-0.20-mapreduce/hadoop-core-2??.0.0-mr1-cdh4.4.0.jar:/usr/lib/hadoop-0.20-mapreduce/hadoop-test-2.0.0-mr1-cdh4.4??.0.jar:/usr/lib/hadoop-0.20-mapreduce/hadoop-test.jar:/usr/lib/hadoop-0.20-mapreduce/hadoop-tools-2.0.0-mr1-cdh4.4.0.jar:/usr/lib/hado??op-0.20-mapreduce/hadoop-tools.jar:/usr/lib/hadoop-0.20-mapreduce/lib/*jar:/usr/lib/hadoop/hadoop-common.jar:/usr/lib/hadoop/hadoop-common-2.0.0-cdh4.4.0.jar

最后2个jar文件包含PlatformName和FsShell类.仍然没有用.

有人可以帮我解决这个问题吗？

谢谢

Answer 1

hadoop-auth-2.2.0.jar应该在那里为hadoop2.2.0
添加hadoop auth jar为您的版本

Answer 2

Hadoop HADOOP_CLASSPATH 问题

这会有帮助的。

谢谢和问候，
