java.lang.IllegalArgumentException: URI has an authority component

来分析错了：是hdfs-site.xml配置文件中dfs.namenode.name.dir的配置有问题，或者没进行配置

正确的配置是：

进入修改

vim /home/bigdata/Opt/hadoop-2.10.1/etc/hadoop/hdfs-site.xml

		
				dfs.replication
				1
		
		
				dfs.namenode.name.dir
				file:/home/bigdata/Opt/hadoop-2.10.1/tmp/dfs/name
		
		
				dfs.datanode.data.dir
				file:/home/bigdata/Opt/hadoop-2.10.1/tmp/dfs/data
