Re: Cluster name
Hi,
I'd like to up this thread for discussion.
It seems that cluster name could be very useful together with multicast
discovery - do not accept nodes with different cluster name.
By default, let's set cluster name to "DEFAULT_CLUSTER".
Thoughts?

Agree. Looks like a useful feature, especially for testing purposes.

Re: Cluster name

Hi,
The community has just voted to phase out Ignite Web Console:
https://issues.apache.org/jira/browse/IGNITE-13038
GridGain's version of Web Console incorporates all the features of Ignite
counterpart and should support the feature you are checking out. Feel free
to switch to that tool or another monitoring solution.

Hi - Just checking if this feature of naming a cluster from the web console
has been added now? If yes how do we do it?

The system properties are a blackbox that few of the users are aware about. How do we decide where a property should go? Any rule for that?

Re: Cluster name
Posted by Alexey Kuznetsov <ak...@apache.org>.
Alexey,
How we would handle situation if first node has one name in sys props and
second has another name or does not have any name?

Re: Cluster name
Posted by Alexey Goncharuk <al...@gmail.com>.

when configuration change is not available).

Re: Cluster name
Posted by Sasha Belyak <rt...@gmail.com>.
Cluster name - yes
Limit cluster building by cluster name - yes
env/system property - no, let's add cluster name to ignite configuration.
