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

<configuration>
		<property>
				<name>dfs.replication</name>
				<value>1</value>
		</property>
		<property>
				<name>dfs.namenode.name.dir</name>
				<value>file:/home/bigdata/Opt/hadoop-2.10.1/tmp/dfs/name</value>
		</property>
		<property>
				<name>dfs.datanode.data.dir</name>
				<value>file:/home/bigdata/Opt/hadoop-2.10.1/tmp/dfs/data</value>
		</property>
</configuration>
