I had the same error. I got this error because of the Hadoop configuration file named core-site.xml. It might be possible that your core-site.xml contains the code given below:

<configuration>
<property>
<name>fs.default.name</name>
<value>hdfs://localhost:9000 </value>
</property>
</configuration>

The error occurred because of the space present between 9000 and </value>. To overcome, replace the core-site.xml with the following snippet:

<configuration>
<property>
<name>fs.default.name</name>
<value>hdfs://localhost:9000</value>
</property>
</configuration>

You have to remove the space between 9000 </valve>, that should look like 9000</value>.
