Subject [jira] Commented: (HBASE-3431) Regionserver is not using the name given it by the master; double entry in master listing of servers
Date Mon, 07 Feb 2011 21:14:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-3431?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12991612#comment-12991612
] 

ryan rawson commented on HBASE-3431:
------------------------------------

one thing to consider is a lot of the network code attempts to figure
out what is the 'primary ip' then bind to just that IP.

would it make sense to bind to * instead? (ie: 0.0.0.0) Why not accept
RPCs on all interfaces? If security is a concern, I think SASL and
host level firewall controls are a better way to address that, rather
than bake it in HBase.  That way it won't really "matter" what our IP
is, whatever IP the master 'sees' us as could be used as what to stuff
in the META.  Then we could use the registration name to identify dead
hosts, etc, etc.

tells it use another name but we seem to go ahead and continue with our original name.
