Zephyr Guo created YARN-5207:
--------------------------------
Summary: Web-Proxy should support multi-homed systems.
Key: YARN-5207
URL: https://issues.apache.org/jira/browse/YARN-5207
Project: Hadoop YARN
Issue Type: New Feature
Components: webapp
Affects Versions: 3.0.0-alpha1
Reporter: Zephyr Guo
Fix For: 3.0.0-alpha1
{{WebAppProxyServlet}} use {{HttpClient}} to download URL for AppMaster.
{{HttpClient}} bind the local address according to
{{yarn.web-proxy.address}}.{{HttpClient}} should use the independent address
for following situation:
There are two network cards.{{CardA}} for user to access cluster, {{CardB}} for
cluster inner communication.User can only access {{Web-Proxy}} by {{CardA}}.
{{CardA}} can't ping {{CardB}}.
So we have to bind {{Web-Proxy}} to {{CardA}}, and then specify {{HttpClient}}
use {{CardB}}.
