请帮忙。我在网上搜索，找不到任何东西。大部分类似的问题都没有答案或无益。运行Hadoop示例Jar
嗨我试图运行Hadoop Pi的例子。我的设置完成并成功。我运行bim/hadoop dfs -ls，但没有出错。
但这：
Sanjanas-MacBook-Pro:hadoop sanjanaagarwal$ /usr/local/Hadoop/bin/hadoop jar $HADOOP_HOME/hadoop-examples-*.jar pi 10 100
Number of Maps = 10
Samples per Map = 100

我hadoop-env.sh是所有设置。仍然不知道这里的问题是什么..请提及命令，如果有什么要检查，因为我对Linux非常新。谢谢
你可以粘贴到你的问题运行'hadoop fsck /' –
@HenryShen输出正如我在问题中提到，我已经做了很多在线搜索，没有任何帮助。 –
