--------------------------------------
Summary: Network issues can cause persistent RM UI outage
Key: YARN-4767
URL: https://issues.apache.org/jira/browse/YARN-4767
Project: Hadoop YARN
Issue Type: Bug
Components: webapp
Affects Versions: 2.9.0
Reporter: Daniel Templeton
Assignee: Daniel Templeton
Priority: Critical
If a network issue causes an AM web app to resolve the RM proxy's address to
something other than what's listed in the allowed proxies list, the AmIpFilter
will 302 redirect the RM proxy's request back to the RM proxy. The RM proxy
will then consume all available handler threads connecting to itself over and
over, resulting in an outage of the web UI.
