Tom White commented on HADOOP-1638:
-----------------------------------
The hadoop-site.xml is created on node startup using the hostname passed in as
user data (which comes from the env file). See
src/contrib/ec2/bin/image/hadoop-init. Is the problem that something is
corrupted - what are the #</property> lines above? Or is it that the wrong
hostname is substituted?
> Master node unable to bind to DNS hostname

> Reporter: Stu Hood
> Priority: Minor
> Fix For: 0.13.1, 0.14.0, 0.15.0

> With a release package of Hadoop 0.13.0 or with latest SVN, the Hadoop
> contrib/ec2 scripts fail to start Hadoop correctly. After working around
> issues HADOOP-1634 and HADOOP-1635, and setting up a DynDNS address pointing
> to the master's IP, the ec2/bin/start-hadoop script completes.
> But the cluster is unusable because the namenode and tasktracker have not
> started successfully. Looking at the namenode log on the master reveals the
> following error:
> #2007-07-19 16:54:53,156 ERROR org.apache.hadoop.dfs.NameNode:

> The master node refuses to bind to the DynDNS hostname in the generated
> hadoop-site.xml. Here is the relevant part of the generated file:
> #<property>
> # <name>fs.default.name</name>
> # <value>blah-ec2.gotdns.org:50001</value>
> #</property>
> #
> #<property>
> # <name>mapred.job.tracker</name>
> # <value>blah-ec2.gotdns.org:50002</value>
> #</property>
> I'll attach a patch against hadoop-trunk that fixes the issue for me, but I'm
> not sure if this issue is something that someone can fix more thoroughly.
