But in my logs I get the message found in post:
<https://forums.couchbase.com/t/havent-heard-from-a-higher-priority-node-or-a-master-so-im-taking-over/5924>

```
Haven't heard from a higher priority node or a master, so I'm taking over.  mb_master 000   ns_1@10.200.0.10    1:07:38 AM Tue Feb 7, 2017

```

and

```
Somebody thinks we're master. Not forcing mastership takover over ourselves mb_master 000   ns_1@10.200.0.10    1:07:28 AM Tue Feb 7, 2017

```

I am having trouble finding what the master does, because any search about a master results in the comment of couchbase not having a master node.
