NPE when field index turned off with scaled_float type #23487
Description
Elasticsearch version: 5.2.2
Plugins installed: []
JVM version: openjdk 1.8.0_121
OS version: Ubuntu 16.04
Description of the problem:
Turned off the indexing of one scaled_float field in my mapping and in Kibana the index pattern broke after refreshing the fields.
The result of it in Discover view are these errors: Saved "field" parameter is now invalid. Please select a new field. Discover: "field" is a required parameter.
But the underlying problem is a null pointer exception.
Steps to reproduce:
- Create an index template mapping with at least one property like this:
"price": {
"type": "scaled_float",
"scaling_factor": 100000,
"index": false
}
- I also set "index.mapper.dynamic" to false in the template settings, but don't think it's required here. I also have a date field.
- Index a document using the template.
- Try to refresh the field list of the index pattern in Kibana or create a new one. None of the fields will be selected as searchable or aggregatable.
- Discover view will instantly show the errors.
- Check the elasticsearch log for a NPE.
Changing the type to float or double works, and also leaving the index option on default true eliminates the problem, but I really need both index off and scaled_float type.
