[Fatal Error] core-site.xml:1:1: Premature end of file

Q: I'm working through it now and obtained the node and got in through VNC. When I ran hadoop dfsadmin -report, I got the error shown in the attached screenshot. So, I'm not even getting to the 0 node problem. Any idea what is going on?

A: It seems your ~/.hadoop2/conf/core-site.xml is corrupted.

Please check if it is the same as following:

hr4757@login1:~$ cat ~/.hadoop2/conf/core-site.xml

<?xml version="1.0"?>

<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

<!-- Put site-specific property overrides in this file. -->

<configuration>

<configuration>

<property>

<name>fs.default.name</name>

<value>hdfs://c201-124:9000</value>

</property>

</configuration>

</configuration>

Use the conf file attached below:

upload the attached file to {your home}/.hadoop2.
