I'm creating a custom mapper plugin under elasticsearch version 2.4.0 but I have this warning in the log every time I insert new data

> `no index mapper found for field [....] returning default posting formats`

I search for this but all I can find is about upgrades issues, nothing like this. Any ideas was wrong? Thanks.
