> 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:
> {code}
