I am trying to add a second couchbase 2.5.1 node to a couchbase 2.5.1 cluster that has one node currently in it. When I created the new node I first tried to add it to the existing cluster during configuration, but it gave me this error:
Attention - Prepare join failed. Authentication failed.
Verify username and password. Got HTTP status 401 from REST call post
to http://127.0.0.2:8091/engageCluster2. Body was: []
I then created it in a new cluster and tried to add it to the existing cluster from the admin console of the existing console by clicking ‘Add Server’ but I got the exact same error (and I made sure to specify the credentials for the new cluster I had just created when trying to add). I came across this bug report while searching up the original problem: https://issues.couchbase.com/browse/MB-11895?page=com.atlassian.jira.plugin.system.issuetabpanels:worklog-tabpanel
Does this mean I can’t create a cluster with couchbase 2.5.1 nodes?
