Getting "rebalance-incomplete" event before the cluster enters the balanced state.
Attaching operator and couchbase cluster logs with this.

Closing this out since it's due to networking issues in the test environment.
Closing this, since it relates to network flakiness in K8S environment
From the server logs:
[ns_server:error,2018-08-05T11:19:39.949Z,ns_1@test-couchbase-k2zd9-0000.test-couchbase-k2zd9.ashwin.svc:<0.19219.0>:ns_single_vbucket_mover:spawn_and_wait:105]Got unexpected exit signal {'EXIT',<0.19239.0>,

{error,
{{{badmatch,
{error,
{{badmatch,{error,nxdomain,}}
So this appears to be a DNS issue, and nothing to do with the operator. You may want to raise this with the NS server team to double check. One suggestion is to retry the connection attempt a few times with a fibonaci back off before declaring that you cannot connect, as it's a transient error evidenced by the fact that a subsequent rebalance succeeds.
