I have an 3 node ES Cluster (version 5.6.3). I have deleted the data from each Node and tried to bring up the cluster (as I am still experimenting with the cluster, the data is not important).
I get the below error:
[2018-01-05T09:41:26,410][ERROR][o.e.x.s.a.e.ReservedRealm] [c2-5a-c1-c2-d3-93] failed to retrieve password hash for reserved user [elastic]
[2018-01-05T09:41:26,411][WARN ][o.e.x.s.a.AuthenticationService] [c2-5a-c1-c2-d3-93] An error occurred while attempting to authenticate [elastic] against realm [reserved] - ElasticsearchSecurityException[failed to authenticate user [elastic]]
How can I fix this? With the data deleted, I would have thought this would been seen as a clean cluster?
I can't seem to amend the elastic user password through ../bin/x-pack/users command as it is a reserved user. It seems the password is corrupt? How can I reset this?
