Why are we getting this error?
Elastic Search Version: (on all 4 nodes)
“version” : {
“number” : “5.5.1”,
“build_hash” : “19c13d0”,
“build_date” : “2017-07-18T20:44:24.823Z”,
“build_snapshot” : false,
“lucene_version” : “6.6.0”
},
Graylog Version: (2 nodes)
Graylog 2.3.1+9f2c6ef
Could this be because we have a Kibana connected to the cluster as
node.master: false
node.data: false
ES Version of Kibana
“version” : {
“number” : “5.6.3”,
“build_hash” : “1a2f265”,
“build_date” : “2017-10-06T20:33:39.012Z”,
“build_snapshot” : false,
“lucene_version” : “6.6.1”
}
Should we downgrade the ElasticSearch of Kibana?
Or should we upgrade Graylog’s ElasticSearch?
Speaking of which is Graylog compatible with ElasticSearch 5.6.3?
We are on Graylog 2.3.1 AWS Image (old image, gone through several Graylog upgrades)
Thanks
