Stardog Cluster: By Licese Limited nodes Number!?

[samir]

Hi,

I am  hopping that the Stardog-2.2.4 (Dev 30 days) cluster setting could be smoother and have started to set a cluster of 4 and then 3 nodes.

In all cases, after starting ZK on all nodes,  I could start Stardog just on the first 2 nodes, any 2 nodes on which I firstly start Stardog on .

Here are the last lines of the error log:

Is there a limitation for the nodes number or the error could be caused by something else? 

In advance thank you very much for any hints,

Dear Samir,

Currently the license does limit the size of the cluster to two nodes. We are reviewing this and might change this policy in the near future.

Dear Hector,

Thank you very much for your response.

Shouldn't Stardog cluster have three or more nodes!? Is this limitation a new Stardog feature?

A very clear example with three nodes is given in the Documentation without any warning that we can NOT use it!

Isn't this a contradiction!?

I have invested so much time and effort to do a task with 4 Stardogdog nodes for testing purposes.

Could you please provide me with a hint or a solution how to continue?

In advance thank you very much.

Best regards,

Samir

Its an unfortunate oversight that we'll repair after the holidays in the US.

Cheers,

Hopefully, you'll as soon as possible repair the license, not the documentation :-)

Thanks & cheers,

Samir

Yes, of course.
