this error occured when i use logstash to collect logs and output it to es ;

i use logstash on my linux server and logstash version is 6.0.0 with es and kibana ;

also my es shows that "unable to load JNA native support library, native methods will be disabled." when id start es;

following my logstash log:  
[2017-12-01T14:28:55,010][ERROR][logstash.outputs.elasticsearch] Encountered a retryable error. Will Retry with exponential backoff {:code=\>403, :url=\>"[http://localhost:9200/\_bulk](http://localhost:9200/_bulk)"}

how can i solve this problem，and what caused this ?

The 403 error indicates a permission problem. Make sure the user used by Logstash has sufficient permissions in Elasticsearch. I don't think this is related to the JNA library problem but you'll probably want to solve that anyway so I'd start there.
