> ------------------------------------------------

> Key: HDFS-17501
> URL: https://issues.apache.org/jira/browse/HDFS-17501
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: webhdfs
> Reporter: Ye Ni
> Assignee: Ye Ni
> Priority: Minor
>
> Provide a WebHDFS parameter so the redirect URL to a datanode can have an
> option on hostname or IP address.
> This takes effect for both NameNode and Router WebHDFS. Default value is
> false, which is consistent with current behavior.

> HttpFS doesn't need this change because HttpFS always uses the same URI as
