Przemyslaw Pastuszka updated WHIRR-749:
---------------------------------------
Attachment: hadoop.properties
> 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
> Attachments: hadoop.properties
>
>
> 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}
