[jira] [Commented] (YARN-5080) Cannot obtain logs using YARN CLI -am for either KILLED or RUNNING AM

["Xuan Gong (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/YARN-5080?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15282240#comment-15282240 ] 

Xuan Gong commented on YARN-5080:
---------------------------------

The issue is that we use the wrong way to get RM web address.
In LogsCLI#getAMContainerInfoForRMWebService:
{code}
    String webAppAddress =
        WebAppUtils.getWebAppBindURL(conf, YarnConfiguration.RM_BIND_HOST,
          WebAppUtils.getRMWebAppURLWithScheme(conf));
{code}
we should directly use
{code}
String webAppAddress = WebAppUtils.getRMWebAppURLWithScheme(conf);
{code}
