Setting index.mapper.dynamic was removed after version 6.0.0

[sascha_a]

Hello,

we have trouble after elasticsearch 7.0.1 upgrade (from 6.7).
The cluster itself exists since version 5.4 or even earlier always rolling upgrading.

It always complains about:

"Setting index.mapper.dynamic was removed after version 6.0.0"

this does happen it seems on every index create and also breaks kibana (https://github.com/elastic/kibana/issues/36000)

we tried to remove the settings:

curl -X PUT "10.0.2.1:9200/_settings" -H 'Content-Type: application/json' -d'
{
  "index.mapper.dynamic":null
}
'
{"acknowledged":true}

which is acked, but it still doesnt work out to create indexes.

curl -X PUT "10.0.2.1:9200/twitter"

{"error":{"root_cause":[{"type":"remote_transport_exception","reason":"[search-6][172.18.0.2:9300][indices:admin/create]"}],"type":"illegal_argument_exception","reason":"Setting index.mapper.dynamic was removed after version 6.0.0"},"status":400}`

/_settings
doesnt say anthing about index.mapper.dynamic, also theres nothing in the env for the servers..

please help out asap, we need kibana running in our cluster !

Is it mentioned in an index template? I.e. do you see this setting mentioned anywhere in the output of curl "10.0.2.1:9200/_template?pretty&flat_settings"?

hey @DavidTurner

thanks for the prompt answer!

We getting closer, yes it is:

curl -s "10.0.2.1:9200/_template?pretty&flat_settings" | grep mapper
      "index.mapper.dynamic" : "false"
      "index.mapper.dynamic" : "false",
      "index.mapper.dynamic" : "false",

how to get rid of it?

[sascha_a]

solved it by deleting those templates.

anyways should this not somehow mentioned in the upgrade process or did it miss it? especially the template part was important..
