Hi,
I tried upgrading my Elasticsearch 5.6.5 to 6.4.0 on Centos 7 using the instructions describe [here](https://www.elastic.co/guide/en/elasticsearch/reference/current/rolling-upgrades.html) but everytime I start the service it fails with this exception:
```

I've seen this same problem in another topic ([Upgrade from 5.6 to 6.2.1: Failed to read local state](https://discuss.elastic.co/t/upgrade-from-5-6-to-6-2-1-failed-to-read-local-state/121630)), but it's unsolved.
Any idea how to solve it?
