> Key: HDFS-62
> URL: https://issues.apache.org/jira/browse/HDFS-62
> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: Carlos Valiente
> Assignee: Todd Lipcon
> Priority: Minor
> Attachments: HADOOP-5626.patch, hadoop-5626.txt

> I have set up {{dfs.secondary.http.address}} like this:
> {code}
> <property>
> <name>dfs.secondary.http.address</name>
> <value>secondary.example.com:50090</value>
> </property>
> {code}
> In my setup {{secondary.example.com}} resolves to an IP address (say,
> 192.168.0.10) which is not the same as the host's name (as returned by
> {{InetAddress.getLocalHost().getHostAddress()}}, say 192.168.0.1).
> In this situation, edit log related transfers fail. From the namenode log:
