Subject [jira] [Commented] (YARN-3714) AM proxy filter can not get proper default proxy address if RM-HA is enabled
Date Wed, 27 May 2015 06:46:17 GMT

    [ https://issues.apache.org/jira/browse/YARN-3714?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14560500#comment-14560500
] 

Masatake Iwasaki commented on YARN-3714:
----------------------------------------

In non-HA settings, if users do not explicitly set the {{yarn.resourcemanager.webapp.address}}
in configuration, {{WebAppUtils#getResolvedRMWebAppURLWithoutScheme}} returns RM webapp address
based on the value of {{yarn.resourcemanager.hostname}} via the default value set by yarn-default.xml.
{noformat}
  <property>
    <name>yarn.resourcemanager.webapp.address</name>
    <value>${yarn.resourcemanager.hostname}:8088</value>
  </property>
{noformat}

As a result, WebAppUtils#getProxyHostsAndPortsForAmFilter can return proper proxy address.

This does not apply to {{yarn.resourcemanager.hostname._rm-id_}} in HA mode.

> Default proxy address could not be got without setting {{yarn.resourcemanager.webapp.address._rm-id_}}
and/or {{yarn.resourcemanager.webapp.https.address._rm-id_}} explicitly if RM-HA is enabled.
