             Summary: Invalid hostname in fs.default.name in core-site.xml on ec2 cluster
                 Key: WHIRR-749
                 URL: https://issues.apache.org/jira/browse/WHIRR-749
             Project: Whirr
          Issue Type: Bug
    Affects Versions: 0.8.2
            Reporter: Przemyslaw Pastuszka


Tried to provision ec2 cluster using hadoop.properties (attached) file and whirr-0.8.2. Provisioning ended without any exception, but actually hadoop cluster was not usable - this was due to wrong addresses being configured in core-site.xml:
{code}
 <property>
    <name>fs.default.name</name>
    <value>hdfs://hadoop-37f7a94f:8020/</value>
  </property>
</configuration>
{code}

but system doesn't know such hostname:

{code}
$ ping hadoop-37f7a94f
ping: unknown host hadoop-37f7a94f
{code}

As a result none of hadoop processes is working on the cluster - as a proof, that hostname is the root cause of the problem, here's excerpt from namenode logs:
