----------------------------------------------
Summary: Hadoop NameNode Web UI throws "Failed to retrieve data
from /jmx?qry=java.lang:type=Memory, cause:" When running behind a proxy
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
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/
