Cluster red and node name wrong after rolling restart

I just upgraded a three node cluster from 2.2.0 to 2.3.3 using the rolling restart method advised. The first two nodes were no problem, but after upgrading the third and restarting Elasticsearch the cluster turned red.

The node joins the cluster with name that's 22 apparently random characters and it says it has no shards.

Shutdown and restarted Elasticsearch on all nodes. All have rejoined the cluster but with random names. Kibi reports that the Elasticsearch version is still 2.2.0 rather than 2.3.3.


I realized the Marvel index was bad. I was running Kibi and did not allow for the fact that Kibi is a version behind so plugins are incompatible (rookie mistake!).

Uninstalled the marvel plugins for Elasticsearch and deleted the .marvel* indices and the cluster health (as queried via rest api) is green.

Will have to wait for the next version of Kibi to run Marvel with that.
