Strange warning when putting mappings

Elastic Stack Elasticsearch
1

I am seeing strange warnings (see below) when putting mappings
containing 'dynamic_templates'. The mapping seems perfectly right and
if you closely look at the warning below you find that only the order
of the 'match' and 'match_mapping_type' is different. Content wise the
mappings are the same. Is this a bug in Elastic Search? Is there
anything I can do on my end to avoid the warning (as it is badly
spamming my log files)?

Heya,

Its not something that breaks the system, its just a warning that extra processing of mapping is done (which should not really be done). I simply need to fix it (the warning is there so if I miss something, it will bubble up through the users :slight_smile: ). Can you gist a recreation of this so it will be simpler for me to fix it?

Thanks!, pushed a fix: Mapper: Using `dynamic_template` can result in warning of parsed and original source difference (resulting in excessive mapping parsing) · Issue #764 · elastic/elasticsearch · GitHub.
