How to solve field in mapping but already used in other types

Elastic Stack Elasticsearch
3

Only one es, topbeat ---> logstash1, packetbeat---> logstash2, while logstash is output to the same es, such data will be merged into logstash-*.
It will report the error above, unless the creation of multiple es
java.lang.IllegalArgumentException: Field [proc] is defined as a field in mapping [mysql] but this name is already used for an object in other types

thanks.
