Metricbeat 5.1.1 "unsupported parameters" es2x template

[JPvRiel (Jean-Pierre)]

Metricbeat 5 is no longer working with ES 2.x. There are document mapping issues.

Config (I also tried bare bone default, same issue)

output.elasticsearch:
  enabled: true
  hosts: ['<hostname>']
  protocol: http
  2x.enabled: true
 compression: none

Output

PS C:\Program Files\Metricbeat> .\metricbeat.exe -e
...

In 2x template

        "throttle": {
          "properties": {
            "pct": {
              "type": "float"
            }
          }
        },

This should work as per https://www.elastic.co/support/matrix#show_compatibility

Thanks for bringing this up. It should definitively be compatible with 2.x I'm kind of surprised that it throws an error on float as float is also supported in 2.4. Can you share your metricbeat and elasticsearch config? Is this a new elasticsearch setup or did you upgrade it from a previous version?
