Elasticsearch version: 5.6
We are trying to upgrade our cluster from ES 5.6 to ES 6.x (currently hosted on ElasticCloud) and we are using the Upgrade Assistant in the Management section of Kibana.
We have managed to solve all issues highlighted by the Cluster checkup, except for one:
Details: [node[instance-0000000022] used these script-security settings:[script.inline, script.stored, script.file, script.engine.painless.inline, script.engine.expression.inline, script.engine.mustache.inline]]
Looking at the documentation I find the following piece concerning updates for scripting settings:
All of the existing scripting security settings have been removed. Instead they are replaced with script.allowed_types and script.allowed_contexts.
The setting script.max_compilations_per_minute has been replaced with script.max_compilation_rate, which consists of a rate and a time value, for example 75/5m
but it is not clear how to address this compatibility issue. Has anyone been through the same process facing our current problem?
