Subject [jira] [Commented] (YARN-1994) Expose YARN/MR endpoints on multiple interfaces
Date Thu, 14 Jul 2016 18:02:20 GMT

    [ https://issues.apache.org/jira/browse/YARN-1994?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15377882#comment-15377882
] 

Karthik Kambatla commented on YARN-1994:
----------------------------------------

[~arpitagarwal] - what are your thoughts on setting the default value for RM and ATS bindhosts
to 0.0.0.0? Wanting to listen on all interfaces seems like what most users would want to do.
If we think changing this would be incompatible in 2.x, how about 3.0?

> 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.
