この例外に関して多くの投稿があったことは承知していますが、この問題を修正することはできません。クラスパスを編集して解決する必要があると思います。Hadoop インフラストラクチャで DistMap というプログラムを実行しようとしています。これは私が得ているエラーです。

どのJavaが言う
/usr/java/jdk1.6.0_32/bin/java
echo $CLASSPATH は空白行を与えます
猫 ~/.bash_profile 言う
cat ~/.bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin
export PATH

最後の 2 つの jar ファイルには、これらのクラス PlatformName と FsShell があります。それでも機能しません。
誰でもこの問題を解決するのを手伝ってもらえますか?
ありがとう
