Hi @jasontedor,

I posted some log in [this port](https://discuss.elastic.co/t/elasticsearch-5-6-3-upgrade-to-6-0-node-will-not-start-failed-to-read-local-state/108252/22)... , if you can, help me solve this problem.

Sumary:

- Upgrade from 5.6.2 to 6.0.0, fail becasue ML job .
- Downgrade from 6.0 back to 5.6.2 -\> delete ML job but cant not start cluster.

I sent log for **dkyle**. So we can move to [thread](https://discuss.elastic.co/t/elasticsearch-5-6-3-upgrade-to-6-0-node-will-not-start-failed-to-read-local-state/108252/22) and find a way solve this problem.  
P/s: I sent log for you in private message.

Thanks for all
