I am working with hadoop for the first time, and I am following
instructions at
http://www.michael-noll.com/tutorials/running-hadoop-on-ubuntu-linux-single-node-cluster/
I am having problems starting the secondarynamenode daemon. The error
message in
/var/log/hadoop/hduser/hadoop-hduser-secondarynamenode-master.out is
Exception in thread "main" java.lang.IllegalArgumentException: Does not
contain a valid host:port authority: file:///

I googled the error message and came across HDFS-2515, which says that I
might get that error message if the fs.default.name property name had an
incorrect value, but I think my value is okay.
My core-site.xml file is :
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<!-- Put site-specific property overrides in this file. -->
<configuration>
<property>
<name>hadoop.tmp.dir</name>

<description>A base for other temporary directories.</description>
</property>
<property>
<name>fs.default.name</name>
<value>hdfs://localhost:54310</value>
<description>The name of the default file system. A URI whose
scheme and authority determine the FileSystem implementation. The
uri's scheme determines the config property (fs.SCHEME.impl) naming
the FileSystem implementation class. The uri's authority is used to
determine the host, port, etc. for a filesystem.</description>

Does anybody have a suggestion for how to further troubleshoot this
problem, please?
Thank you,
