Hi, I'm trying to perform a rolling upgrade (5.6 to 6.6) on 3 nodes. I successfully upgraded the first node according to the instructions in: https://www.elastic.co/guide/en/elasticsearch/reference/current/rolling-upgrades.html
I also started the new version of kibana on that node (node 1).
Now, I'm trying to upgrade the next node. I see that it is shutdown, so i cant disable shard allocation on it.
When I try to directly start elasticsearch 6.6 on this node (using the SAME config as the prev node), i get this error:
