我使用这个命令在hadoop中运行wordcound示例。

hadoop jar /usr/local/Cellar/hadoop/3.0.0/libexec/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.6.5.jar wordcount inputWiki/Wiki_data_100MB outputWiki0301

我得到了如下的错误信息。

2018-03-01 18:54:14,845 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
2018-03-01 18:54:16,107 INFO beanutils.FluentPropertyBeanIntrospector: Error when creating PropertyDescriptor for public final void org.apache.commons.configuration2.AbstractConfiguration.setProperty(java.lang.String,java.lang.Object)! Ignoring this property.*

我以前用过这个命令运行过类似的文件,效果很好。有人能帮我吗?
更新以下结果:

错误是这样的
输入路径不存在:hdfs://localhost:8020/user/xujingjing/inputgurtenberg0302/gurtenberg.txt
所以使用

hdfs dfs -mkdir -p /user/xujingjing/inputGurtenberg0302/
hdfs dfs -copyFromLocal \
   /path/to/gurtenberg.txt \
   /user/xujingjing/inputGurtenberg0302/

我以前用这个命令运行过类似的文件
初始命令中的行使用完全不同的文件
