Subject [jira] [Commented] (KARAF-1311) cluster:group-list command returns unresolvable node name
Date Fri, 11 May 2012 14:14:50 GMT

    [ https://issues.apache.org/jira/browse/KARAF-1311?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13273285#comment-13273285
] 

Sergey Lysenko commented on KARAF-1311:
---------------------------------------

Ok, now both cluster:node-list and cluster:group-list have same node names for regular and
mDNS-ed hosts, and mDNS-ed is available through it's {hostname}.local:port name.
So this issue is fixed indirectly.

karaf@trun> cluster:node-list 
   No. Host Name             Port ID

>          Components: cellar-core
>    Affects Versions: cellar-2.2.3
>            Reporter: Sergey Lysenko
>            Assignee: Jean-Baptiste Onofré

>
> There are two test hosts: 10.7.17.97 and 10.7.17.98, without any local DNS and with some
diffrerent contents in /etc/hosts file
> The host 10.7.17.97 runs avahi-daemon mDns service, so it's hostname is resolved to <hostname>.local
> The host 10.7.17.97 is visible and pingable by terms of OS from shell prompt.
> Both hosts has one karaf instance running with installed cellar feature
> Output of cluster:node-list command displays correct and resolvable node names (which
is different for these two hosts and finely resolvable on each of then),
> while output of cluster:group-list outputs uses hostname resolved by mDns for the 10.7.17.97
host.
> Node name which contains resolved hostname can not be used for access to this node while
using other commands.
> It is expected that node names in cluster:group-list are resolvable, same as in output
of cluster:node-list command.
> Either output of cluster:group-list should be changed, or access to nodes through hostnames
resolved by mDns should be provided
> See screenshot for reference.
