While transferring data with Logstash, there is an increase in write threads on the node that is not in the output host list that I specified. I do not want to transfer data over a single node. This causes me to experience slowness. I want to distribute to multiple nodes. Do I need to specify this elsewhere than in the host list? ---

the hosts works as a [cordinating node](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-node.html#coordinating-node) to distribute documents to appropriate data nodes containing the shards of the target index. This is a problem of [shard allocation](https://www.elastic.co/guide/en/elasticsearch/reference/current/index-modules-allocation.html) of Elasticsearch cluster. And also, please recheck the `number_of_shards` settings of the target index is more than 1. ---
