Subject [jira] [Updated] (YARN-1994) Expose YARN/MR endpoints on multiple interfaces
Date Mon, 28 Jul 2014 12:09:39 GMT

     [ https://issues.apache.org/jira/browse/YARN-1994?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Craig Welch updated YARN-1994:
------------------------------

    Attachment: YARN-1994.11.patch

Fixed bug, YarnConfiguration.getSocketAddr checks in ha cases to see which rm it was on, this
was no longer active in earlier versions of the patch.  Simplified logic, removed many unnecessary
changes in earlier patch versions, added some tests.   With this patch, logic should be to
act as before in the absence of any bind-host, in the presence of bind-host, only for the
listening process, port is retrieved from address and used with bind-host to bind, all other
address/configuration paths should now be unchanged by the patch.

> YARN and MapReduce daemons currently do not support specifying a wildcard address for
the server endpoints. This prevents the endpoints from being accessible from all interfaces
on a multihomed machine.
> Note that if we do specify INADDR_ANY for any of the options, it will break clients as
they will attempt to connect to 0.0.0.0. We need a solution that allows specifying a hostname
or IP-address for clients while requesting wildcard bind for the servers.
