我刚刚安装了Hadoop-2.2.0。我尝试了“>这个链接的WordCount示例,但是我收到了这个错误。我该如何解决?

hadoop$ bin/hadoop hdfs -copyFromLocal in /in
Exception in thread "main" java.lang.NoClassDefFoundError: hdfs
Caused by: java.lang.ClassNotFoundException: hdfs

我相信你要找的命令是:

hdfs dfs -copyFromLocal in /in

答案 1 :(得分:0)

尝试,

<强> copyFromLocal

用法: hadoop fs -copyFromLocal <localsrc> URI

例如: hadoop$ bin/hadoop fs -copyFromLocal in /in

与put命令类似,但源仅限于本地文件引用。
