Subject [jira] [Commented] (YARN-1590) _HOST doesn't expand properly for RM, NM, ProxyServer and JHS
Date Mon, 02 Jun 2014 20:37:03 GMT

    [ https://issues.apache.org/jira/browse/YARN-1590?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14015862#comment-14015862
] 

Karthik Kambatla commented on YARN-1590:
----------------------------------------

Just ran into this. If I am not mistaken, in the following snippet, we intended to use DEFAULT_PROXY_PORT
instead of DEFAULT_RM_PORT. Correct? 
{code}
     PROXY_PREFIX + "address";
+  public static final int DEFAULT_PROXY_PORT = 9099;
+  public static final String DEFAULT_PROXY_ADDRESS =
+    "0.0.0.0:" + DEFAULT_RM_PORT;
{code}

YARN-2119 has been filed to fix this.

> _HOST is not properly substituted when we use VIP address. Currently it always used the
host name of the machine and disregard the VIP address. It is true mainly for RM, NM, WebProxy,
and JHS rpc service. Looks like it is working fine for webservice authentication.
> On the other hand, the same thing is working fine for NN and SNN in RPC as well as webservice.
