I am using GetIndexRequest with parameter indices = "*".

val request = GetIndexRequest()
request.indices("*")
val response = client.indices()[request, RequestOptions.DEFAULT]

But I got a warning (migration from ES6 to ES7):

this request accesses system indices: [.kibana], but in a future major version, direct access to system indices will be prevented by default

GetIndexRequest must show all my indices (it can be without system indices).
I tried set request type to "open", but this is not working.

CodePudding user response：

This is just a warning and only means that in future version (ES 8.x), requesting * will not return system indices anymore. So if you don't rely on the current behavior, you're free to ignore this warning.
