Hi,

Before updating my production server from 5.6.5 to 6.x I've tried updating my test cluster, but my cluster entered some weird state.

So I have a cluster where are two PCs with elasticsearch 5.6.5 installed from deb repository.

I've upgraded it to version 6.2.3 from the repository and dpkg confirms it:

```auto
user@whitebox:~$ sudo dpkg -l | grep elasticsearch
ii elasticsearch 6.2.3 all

```

elasticsearch itself reports the new version too:

```auto
root@whitebox:/usr/share/elasticsearch/bin# ./elasticsearch --version
Version: 6.2.3, Build: c59ff00/2018-03-13T10:06:29.741383Z, JVM: 1.8.0_151

```

However, when I make request to IP:9200, it reports old version:

```auto
{
  "name" : "node-whitebox",
  "cluster_name" : "honeypots-dev",
  "cluster_uuid" : "J8Kwgm8cQNamHBGqjazhgw",
  "version" : {
    "number" : "5.6.5",
    "build_hash" : "6a37571",
    "build_date" : "2017-12-04T07:50:10.466Z",
    "build_snapshot" : false,
    "lucene_version" : "6.6.1"
  },
  "tagline" : "You Know, for Search"
}

```

Exactly the same thing happened with the second pc. What I'm doing wrong?

ps: Kibana & logstash successfully upgraded to the 6.2.3 version without problems.

Are you sure you don't still have a 5.6.5 node running? Can you retrieve [nodes info](https://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-nodes-info.html) and look for the version of each node?

It was showing the same - 5.6.5 for both nodes. Eventually, rebooting both PCs solved the issue.
