companion files for manual (rpm) install missing properties in xml configs?

Hi:

I am trying to follow the manual installation procedure (via rpms) documented here:

http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.1.7/bk_installing_manually_book/content/rpm-chap1-9.html

In doing so I triggered an error when following one of the steps that required that I verify that i could format hdfs:

org.apache.hadoop.hdfs.server.namenode.NameNode:
java.lang.IllegalArgumentException: Does not contain a valid host:port authority: file:///

When i googled the cause I came across this bug report > https://issues.apache.org/jira/browse/HDFS-2515
which described how the error is due to an invalid setting for “fs.default.name” in core-site.xml.

I looked at the companion files that the installation manual says i need to download, and noticed that there
was no such property in core-site.xml.

This can be verified by the following little scriptlet:

mkdir /tmp/try ; cd /tmp/try
wget http://public-repo-1.hortonworks.com/HDP/tools/2.1.7.0/hdp_manual_install_rpm_helper_files-2.1.7.784.tar.gz
tar xvzf *gz
cd hdp_manual_install_rpm_helper_files-2.1.7.784/configuration_files/core_hadoop/
grep fs.default.name core-site.xml

So, my question is:

where can i get a set of valid configuration files for the latest hortonworks release ?
The one’s that I wget’d (see above) clearly have some issues.

Maybe I should download the sandbox distribution and grab the files from /etc/hadoop/conf in the corresponding VM? before i try this i figured i’d try to get some advice.

thanks in advance
