BUG-11344: Invalid entry in core-site.xml file
Problem: After extracting the companion files, the included core-site.xml file contains the following invalid entry:
```
{code}
<property>
    <name>fs.defaultFS</name>
    <value>TODO-NAMENODE-HOSTNAME</value>
  </property>
{code}
```
Workaround: Edit the <value> element as follows:
```
{code}
<property>
    <name>fs.defaultFS</name>
    <value>hdfs://TODO-NAMENODE-HOSTNAME:PORT</value>
  </property>
{code}
```
This includes the protocol and port together with the Namenode hostname.
