Fielddata and different types with the same field name in index

Elastic Stack Elasticsearch
3

Thanks for reply.

We have an issue with not working aggregations
(Aggregations stop working silently on elasticsearch 1.4.4)
Could this mapping be an issue (child type field has doc_values: true and parent type does not) ?

           contact: {
              properties: {
                contact_id: { type: 'long', index: 'not_analyzed'}
              }
            },
            event: {
              _parent: { type: :contact },
              properties: {
                user_id: { type: 'long', index: 'not_analyzed' },
                contact_id: { type: 'long', index: 'not_analyzed', doc_values: true },
                data: { type: 'object', index: 'not_analyzed' },
              }
            }
