> Key: HDFS-11994
> URL: https://issues.apache.org/jira/browse/HDFS-11994
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: ui
> Affects Versions: 2.8.0
> Environment: CentOS release 6.9 (Final)
> OpenJDK version "1.8.0_131"
> Hadoop 2.8.0
> Reporter: Sergey Bahchissaraitsev
> Assignee: hemanthboyina
> Priority: Minor
>
> When running behind a proxy Hadoop Web UI throws the following exception
> because it tries to make Ajax requests to the base server URL:
> {code:java}
> Failed to retrieve data from /jmx?qry=java.lang:type=Memory, cause:
> {code}
> A good solution could be to adjust the Ajax URL based on the actual window
> URL using the jQuery Ajax "beforeSend" pre-request callback function:
> http://api.jquery.com/jquery.ajax/
