Hi,

I had cluster with 1 master + 2 data hot + 1 data content.

After changing node role of data hot node to data\_hot, data\_content and performing restart, the node is not joining the cluster due:

> master not discovered yet: have discovered

When I reverting back to data\_hot it is joining properly.

How can I add data\_content role to the data\_hot role?
