Xuan Gong commented on YARN-1525:
---------------------------------

One more thing : 
{code}
setRedirectPath("http://"; + path);
{code}
in RMWebApp:: isStandbyMode(). We need to have either "http" or "https" based 
on the security.

Also, in TestRMFailover, this comment "// Due to the limitation of 
MiniYARNCluster, we couldn't test the case after". I think that the root cause 
is because the org.apache.hadoop.yarn.webapp.Dispatcher is singleton. 



> Web UI should redirect to active RM when HA is enabled.
